(a) In which of the voltaic cells does the copper electrode serve as the cathode? In which of the voltaic cells does the cobalt electrode serve as the anode? (b) Which combination of half-cells generates the highest potential? Which the combination generates the lowest potential?

Question

The following half-cells are available:

Ag+(aq, 1.0 M) and Ag(s)

Zn2+ (aq, 1.0 M) and Zn(s)
Cu2+ (aq, 1.0M) and Cu(s), and

Co2+ (aq, 1.0 M) and Co(s).
Linking any two half-cells makes a voltaic cell. Given four different half-cells, six
voltaic cells are possible. These are labeled, for simplicity, Ag-Zn, Ag-Cu, Ag-Co,
Zn-Cu, Zn-Co, and Cu-Co.
(a) In which of the voltaic cells does the copper electrode serve as the cathode?
In which of the voltaic cells does the cobalt electrode serve as the anode?
(b) Which combination of half-cells generates the highest potential? Which
the combination generates the lowest potential?

7. The following half-cells are available:
Ag* (aq, 1.0 M) and Ag(s)
Cu2* (aq, 1.0M) and Cu(s), and Co2* (aq, 1.0 M) and Co(s).
Linking any two half-cells makes a voltaic cell. Given four different half-cells, six
