I put in the sodium carbonate type as suggested earlier.
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 (along with carbon dioxide and hydrogen) when heated. The copper produced this way isn't well bonded and not very conductive. But in upcoming videos additives may be added to improve the quality of the product.
