Question

The following two half-reactions occur in a voltaic cell:
Ni(s) ---->Ni2+(aq) + 2 e-   (electrode = Ni)
Cu2+(aq) + 2 e- ---->Cu(s) (electrode = Cu)
Which one of the following descriptions most accurately
describes what is occurring in the half-cell containing the Cu
electrode and Cu2+(aq) solution?
(a) The electrode is losing mass and cations from the salt
bridge are flowing into the half-cell.
(b) The electrode is gaining mass and cations from the salt
bridge are flowing into the half-cell.
(c) The electrode is losing mass and anions from the salt
bridge are flowing into the half-cell.
(d) The electrode is gaining mass and anions from the salt
bridge are flowing into the half-cell.
