Cool Science: Silver Chloride Photochemistry
We show the chemistry of photography using silver chloride that we make ourselves from table salt and silver nitrate. Silver chloride has the interesting property that it reacts to light. This photosensitive chemical will decompose into dark silver powder and chlorine. To make it, just mix one gram of silver nitrate made in our previous video ( www.youtube.com ) and half a gram of salt in separate quantities of water. Then mix the two solutions with shaking, this forms silver chloride. Then let it stand for five minutes. This will cause the silver chloride to settle to the bottom. After five minutes pour off the extra liquid. Spread out the silver in a layer onto a piece of paper. Let it dry in darkness as you don't want the light to expose it before you're ready. Once it is dry, place a stencil or template of something you want "photographed" over the silver chloride. You might want to weigh it down with a piece of glass. When you're ready, shine a strong light onto it for ten minutes or so. The silver chloride will darken in the areas that are exposed to light. Remove the glass and template and you will have a negative photo of what you placed over it. The image won't keep forever, eventually the whole thing will darken. This is ofcourse a very simple experiment and modern photography is far superior. Please rate, comment and subscribe! Our website at: www.nurdrage.com
Magnesium Chloride
Magnesium is vitally important and needs to be taken on a daily basis; everybody should take it, because food today is low in magnesium. The reason for that is very simple: plants need very much magnesium to breath. Their chlorophyllic mechanism is fixation of carbonic gas and elimination of oxygen, which is the opposite of what we do. We do this through a mineral, iron is used for the breathing mechanism of red cells. In plants this is done by chlorophyll whose structure is basically magnesium. What happens is that the chemical fertiliser used today is the NPK, nitrogen, phosphorus and potassium. Magnesium in not being replaced in the soil, and in the past, when cities were all made up of houses with septic tanks, the magnesium we eliminated through feces went back to the phreatic zone. However, today everything goes into the rivers and sea, resulting in an increasingly low rate of magnesium in the soil. The two most important functions of magnesium are: it regulates the metabolism of calcium in the body, it fixates the calcium where it should be and eliminates the calcium where it should not be. Therefore, spinal calcifications, joint, artery calcifications happen due to this lack of magnesium. Kidney calcifications, calcium oxalate kidney stones is due to a lack of magnesium. It is enough to give patients magnesium to dissolve kidney stones, provided they are not urate and phosphate ones. if they are calcium oxalate stones then they are due to lack of magnesium ...

Make a Lithium Thionyl Chloride Battery
How to make a Lithium Thionyl Chloride Battery capable of generating 2.8v with enough current to power a LED. Warning: Thionyl Chloride is EXTREMELY toxic and this experiment must be performed in a fumehood by an experienced chemist with proper safety precautions. Lithium thionyl chloride batteries offer excellent shelf life (sometimes over a decade) and energy density. Their main drawback is they are not rechargeable but for low power applications like memory backup they are extremely useful. At very low power levels, they can outlast the device they are installed in, making the recharge issue a non-issue. As seen in this experiment, they are also extremely simple to make. A solution of lithium tetrachloroaluminate in thionyl chloride serves as the electrolyte and the lithium and carbon rods are simply inserted in. The cell can produce up to 3.5volts depending on the purity and quality of the components. Our cell in the video used waste chemicals we had leftover around the lab so the voltage is not that high. But it did produce enough power to light a small light emitting a diode. Commercial cells use lithium foil and spongy carbon for greater current but the concept is still the same.

Extracting caffeine with methylene chloride
In a previous video, I showed how to extract caffeinated water from green coffee beans with supercritical CO2. Here, I show how to extract dry caffeine crystals from the caffeinated water (ie coffee, in this case). I used a vacuum filtration setup to create very strong coffee, then mixed it with methylene chloride in a seperatory funnel. The methylene chloride sinks below the water, taking most of the caffeine with it. By opening the funnel carefully, only the methylene chloride and caffeine can be transferred to a flask where the methylene chloride is boiled away. I then mounted a test tube in a rubber stopped and filled the tube with ice. With the stopped in the flask, I evacuated the flask and applied heat. The caffeine will sublimate and collect on the cold test tube. I scraped off the caffeine and measured the mass.

A Gas Phase Reaction: Producing Ammonium Chloride
In this video I make ammonium chloride from hydrochloric acid and ammonia: HCl + NH3 = NH4Cl This is a particularly interesting reaction because it takes place in the gas phase and produces a very visible white smoke (I included the black backdrop to make this easy to see). This smoke is composed of ammonium chloride microcrystals, and is formed by simply bringing open containers of the reactants close together. This can happen in your home if you store muriatic acid and ammonia cleaner near each other, forming crystals around the rims of the containers. I ended up with about 1g of NH4Cl crystallized from the liquid, but I imagine I could have gotten much more had I captured and condensed the smoke. That would be something interesting to try in the future.

Make Iron (II) and (III) Chloride
Here I demonstrate how to make iron (II) chloride, convert it to iron (III) chloride, and then regenerate it back to iron (II) chloride. We'll be needing both of these reagents in an upcoming video. Very simply, just add some steel wool to hydrochloric acid to produce iron (II) chloride and hydrogen gas: Fe + 2HCl == FeCl2 + H2 The finer the wool, the faster the reaction will be. Iron(II) chloride is rather unstable, and will readily oxidize to iron(III) chloride if left out uncovered. This reaction requires hydrochloric acid, but even so I've heard it's extremely hard to keep iron(II) chloride for any length of time. 4FeCl2 + O2 + 4HCl == 4FeCl3 + 2H2O This reaction can be sped up greatly by introducing oxygen directly into the solution, using 3% drugstore hydrogen peroxide. Finally, iron(III) can be converted back to iron(II) by adding in some more steel wool. Over a few minutes, this causes the solution to change color from brown back to lime green.
Making sodium chloride (NaCl = table salt) by neutralization
In this video, I will show you the reaction of hydrochloric acid and sodium hydroxide. The product is sodium chloride, also known as table salt. Don´t eat the product please ! You will need: - hydrochloric acid - sodium hydroxide - a 100ml container - a 100ml Erlenmeyer flask. The reaction is : NaOH+ HCl=NaCl+H2O. This process is called neutralization. The product is not acidic, not basic, it´s neutralized. You can also evaporate the product to get clear sodium chloride. Thank you for watching. Please, subscribe, rate and comment.
Copper (ii) chloride Aluminium reaction
i take no responsibility for any actions you take in relation to this video i do not recommend or sujest in any way that you attempt to replicate this This is a replacement reaction were elemental aluminium is converted to Aluminium Chloride in this proses. Copper(ii) chloride is a lewis acid so causes the formation of hydrogen gas. This reduces the Copper(ii) ions to elemental copper Incase anyone is wondering the aluminium used was spherical in shape and 200mesh in size 2Al(s) + 3CuCl2 (aq) = 2AlCl3 (Aq) + 3Cu(s) also a side reaction that occurs due to unprotected Al being exposed to water is 2Al (s) + 6H20 (l) = 2Al(OH)3 (aq) + 3H2 (g)

Distillation of Dichloromethane (Methylene Chloride)
Dichloromethane (DCM or methylene chloride) is an organic compound with the formula CH2Cl2. This colorless, volatile liquid with a moderately sweet aroma is widely used as a solvent. Dichloromethane is the least toxic of the simple chlorohydrocarbons, but it is not without its health risks as its high volatility makes it an acute inhalation hazard. Dichloromethane is also metabolized by the body to carbon monoxide potentially leading to carbon monoxide poisoning. Acute exposure by inhalation has resulted in optic neuropathy and hepatitis. Prolonged skin contact can result in the dichloromethane dissolving some of the fatty tissues in skin, resulting in skin irritation or chemical burns.

Elementary Productions: Chromyl Chloride
In this video, synthesis and properties of Chromyl Chloride are demonstrated.
Preparation of Competent Cells Using Calcium Chloride(Amrita University)
Competent cells are those that possess more easily altered cell walls that DNA can be passed through easily. These cells readily incorporate foreign DNA. In order to make bacteria take in the plasmid, they must first be made "competent" to take up DNA. This is done by creating small holes in the bacterial cells by suspending them in a solution with a high concentration of calcium.
Hexaaminenickel(II) Chloride
Here I synthesize a really interesting compound of nickel, with the longest name of any chemical I've made so far! I'll probably be posting how I made my NiCl2 and ammonia solutions in other videos as well, if there's interest. Hexaaminenickel(II) chloride is a complex of nickel with ammonia, and is fairly simple to synthesize. A concentrated solution of nickel(II) chloride is combined with fairly concentrated ammonia to form a deep blue complex while it is in solution. To isolate it in its solid form, acetone is added to reduce the overall polarity of the solution and thus render the complex nearly insoluble. It drops out immediately as a lavender precipitate. Nickel(II) chloride exists in solution and solid form as the hexahydrate - with 6 water molecules associated with it. In solution, the water molecules surround the nickel atom to form the positive cation, and chloride atoms are dissociated as anions. The reaction with ammonia is a simple substitution where the water molecules are replaced with ammonia molecules: [Ni(H2O)6]Cl2 + 6NH3 == [Ni(NH3)6]Cl2 + 6H2O Filtering this precipitate was a breeze - it settles extremely quickly, and since the solution is mostly acetone it evaporates very fast. This was probably the most pleasant filtering experience I've had! I really enjoyed this synthesis, though I don't really have a use for the product. It'll just be something pretty I can put on my shelf, and add to my list of accomplishments!
Copper Chloride with Aluminum
Copper is a noble metal, while aluminum is very reactive. But it's only reactive when the oxide layer is removed. Copper sulfate does not remove this layer, so it hardly reacts at all. Copper chloride happens to remove it effectively, resulting in an impressive reaction rate. The solution boils almost immediately on contact, yielding powdered copper.

Make Manganese(II) chloride from Manganese metal
Manganese(II) chloride describes a series of compounds with the formula MnCl2(H2O)x, where the value of x can be 0, 2, or 4. The tetrahydrate is a pink salt that occurs naturally as the rare mineral scacchite. Most commonly, the term "manganese(II) chloride" refers to the tetrahydrate MnCl2·4H2O, which consists of octahedral trans-Mn(H2O)4Cl2 molecules. The dihydrate MnCl2·2H2O is also known. Many Mn(II) species are characteristically pink, the paleness of the color being characteristic of transition metal complexes with high spin d5 configurations. Very rare mineral scacchite (trigonal) is the natural form, known from Vesuvius.
01 - Synthesis of Ammonium Chloride
I decided to keep it simple for my first upload. I would love any suggestions to make the videos better in the future, so be sure to comment and let me know what you think! Production of ammonium chloride using hydrochloric acid and ammonium hydroxide (ammonia). A simple, exothermic reaction that I decided to make as my first YouTube video. There will be plenty more (and more interesting) videos to come in the following weeks! Be sure to subscribe, rate, and comment! Thanks!! I created this channel for the sole purpose to help spread the interest in science, mainly chemistry. The decline of scientific interest in the United States is rather disappointing. After I cruised YouTube a bit I noticed all the other channels similar to mine and I thought about canceling this channel; however, after thinking about the decline of science, I decided to keep making videos until I just run out of ideas.
