Q. What is the Colour of copper turnings?

Answer

After some time has passed, a solution that is blue in color is produced when copper turnings are introduced to a solution that contains silver nitrate. Copper is the culprit in this case. Copper, when exposed to aqueous silver nitrate, will undergo a chemical reaction that will result in the formation of an aqueous solution of copper (II) nitrate as well as solid silver. As perchemical equation: Cu(s) + 2 AgNO3(aq) --> Cu(NO3)2(aq) + 2 Ag.
