The following reaction occurs at the cathode of an electrochemical cell:
Ni2+(aq) + 2e− → Ni(s)
Which anode reaction would produce a battery with the highest voltage?
(a) Ag(s) → Ag+(aq) + e−
(b) Mg(s) → Mg2+(aq) + 2e−
(c) Cr(s) → Cr3+(aq) + 3e−
(a) Cu(s) → Cu2+(aq) + 2e−
Here, we are going to identify the cathode reaction producing a battery with the highest voltage with the given anode reaction.
Electrochemical cells are the devices which converts chemical energy to electrical energy.
Voltage can be calculated by the following relation:
Ecell = Ecathode –...
