Make Pcb Tinning Solution ("liquid Tin") By Redox Flipping

In this video we make a tinning solution for printed circuit boards. Tinning solutions coat copper metal with a thin layer of tin. This is used to protect them from oxidation as well as make them somewhat easier to solder. To make the solution we first get 1g of lead-free tin solder containing 95% or more of tin metal. Check the MSDS to be sure. Now to the solder we add 10mL of 30% hydrochloric acid. What ...

Make Copper Formate (for Making Copper Conductive Ink)

In this video we make copper formate, a useful precursor to copper conductive ink. We simply dissolve 65g of copper sulfate in 250mL of water and 33g of sodium carbonate in 150mL of water. Then we mix the two together. Copper carbonate hydroxide precipitates and we filter that off. Then we react the copper carbonate hydroxide with formic acid to create copper formate. Copper formate has the useful property that it decomposes into copper metal (...

Make Hydrobromic Acid Revisited 2018

We show how to make hydrobromic acid. Hydrobromic acid is the bromine analogue of hydrochloric acid. While too expensive to use as much as hydrochloric acid, it's often used when the bromine element itself is needed. For example a major use is the synthesis of organobromine compounds like the ones we used in our grignard reactions. To make it, we start with 400mL of water and add to it 250g of sodium bromide. Sodium bromide ...

Make Sodium Silicate (aka "water Glass") From Cat Litter And Drain Opener

In this video we use cat litter and drain opener to make sodium silicate. This will be a valuable precursor to other silicon based chemicals in the future. Most cat litter is made from clay but crystal cat litter or silica cat litter is made from silica gel. Silica gel is amorphous silicon dioxide made by aqueous chemistry is very easy to convert into other silicon compounds. The process is quite straightforward: 60g of silica ...

Remove Coke Can From Coke

In this video we do something really silly and remove a can from the coke it contains. To do the demonstration: First get any soft drink can and using sandpaper, sand off the label. Then open the can and suspend it by the tab in 5% hydrochloric acid. The exact concentration is not critical. The can must be opened or it will rupture as the aluminum is removed. over the course of an hour, the aluminum ...

Make Fire With Potassium Permanganate

In this video we use Potassium Permanganate to start fires. Potassium Permanganate will directly react with various fuels like glycerol, PEG-based brake fluid, and antifreeze, to start fires. All you have to do is mix them. For less reactive fuels like gasoline and mineral oil. It can be mixed and then a few drops of sulfuric acid added to create manganese heptoxide which is a powerful oxidant and will itself ignite most fuels. Related videos: ...
