Question

A rod made of an unknown metal, M, is dipped into a solution containing both X2+ and Z2+ cations.

q1: Will a reaction occur when the rod is dipped into the solution? And if so what solid will begin to form?

q2: If you were to create a voltaic cell using M, which (single) metal would you put as the cathode and anode, respectively?

q3: f Z is Zinc, identify metals X and M
