Question

A 1 M solution of Cu(NO3)2 is placed in a beaker with a strip of Cu metal. A 1M solution of SnSO4 is placed in a second beaker with a strip of Sn metal. A salt bridge connects two beakers and wires to a voltmeter link the two metal electrodes. [ Hint: Charge of nitrate anion is (-1); Charge of Sulfate ion is (-2)]

Which electrode gains mass and which loses mass as the cell reaction proceeds?

Answer 1

Copper electrode gains mass while tin electrode loses mass
