The following equations are half reactions and reduction potentials.

Ag+(aq) + e– mc029-1.jpg Ag(s) has a reduction potential of +0.80 V.
Cr3+(aq) + 3e– mc029-2.jpg Cr(s) has a reduction potential of –0.74 V.

Which statement best compares the substances in these half reactions?
A silver ion gains electrons more easily and is a stronger oxidizing agent than a chromium(III) ion.
A silver ion loses electrons more easily and is a stronger oxidizing agent than a chromium(III) ion.
A silver ion gains electrons more easily and is a stronger reducing agent than a chromium(III) ion.
A silver ion loses electrons more easily and is a stronger reducing agent than a chromium(III) ion.

A silver ion gains electrons more easily and is a stronger oxidizing agent than a chromium(III) ion.

Reason: Ag+/Ag has a more positive reduction potential (+0.80 V) than Cr3+/Cr (−0.74 V), so Ag+ is more readily reduced (gains electrons) and is the stronger oxidizing agent.
