Problem
During the electrolysis of an aqueous chloride solution of a single unknown divalent metal, a current of 1.20 A is applied for 70.0 min. Over the same period, 24.6 mL of H₂(g) (measured at 1 atm and 273 K) is simultaneously evolved at the cathode. If 1.48 g of the metal is deposited, which metal is the most plausible identity?
(a) Cu
(b) Ag
(c) Ni
(d) Zn
