Chemistry

A \"silver\" ring was purchased at a local store. It was stamped\"sterling silver\" which means that it must contain 92.5% by massAg. The remaining 7.5% may technically be any other metal. Copperis typically used for this. This ring was found to be magnetic,which suggests that the non silver part may contain iron or nickelas well. A small amount of the ring is dissolved in nitric acid,making a solution of the nitrate of any metal that would bepresent.

a. What group does each of the four metals belong to?

b. After the removal of the silver as the insoluble chloride,the solution is made basic with 6M NH4OH. If the solution turnsViolet, with no blue color present, what cation was present in thesolution?
