Synthesis Method And Properties Of Copper Aceta

Preparation method in the laboratory:Dissolve 50 g of copper Sulfate pentahydrate in 500 ml of water, filter, and dissolve another 57 g of sodium Carbonate decahydrate in 240 ml of water, heat to 60° C., slowly add the copper sulfate solution with constant stirring. Let stand, filter out the precipitate, wash with hot water until there is no sulfuric acid, put the precipitate in 300ml of water, add 2ml of ammonia water and stir, let stand, pour out the upper layer solution, wash and precipitate several times in this way. Add 180ml of water to the beaker, heat to 60°C, add 22g of glacial acetic acid, and then add the washed basic copper carbonate until there is a little remaining at the bottom of the container.

After filtering, the filtrate is evaporated and concentrated to 1/3 of the original volume, cooled, filtered, washed with 2ml of water, and dried at room temperature to obtain the finished product. The mother liquor continues to evaporate, and 5ml of 25% acetic acid is added when the crystallization is about to come out, and part of the finished product can be obtained. It was 32-35g. [2]

Note: Acetic acid (CH3COOH) can be expressed as HOAc
