2018-3-17 · "CuSO"_4("aq") + "KI(aq)"rarr"no reaction" "CuSO"_4("aq") + "KCl(aq)"rarr"no reaction" There will be no reaction. This is a supposed double replacement reaction (metathesis), in which one product must be an insoluble (solid) precipitate, an insoluble gas, or water. The two possible products from copper sulfate and potassium iodide are copper(II) iodide and
Copper sulphate when dissolved in potassium cyanide reacts with it to form potassium sulphate and cupric cyanide. The reaction of copper sulphate and potassium cyanide is as follows: CuS O 4 + 2 KCN → K 2 S O 4 + Cu ( CN) 2. The cupric cyanide is unstable in nature.
