Question

Use the following half reactions and accompanying standard reduction potentials to determine the best reducing agent.
ERed
Ga3+ + 3e Ga 0.560 V
Be2+ + 2e Be 1.70 V
Pd2+ + 2e Pd +0.987 V
(a) Ga3+
(b) Be2+
(c) Be
(d) Pd2+
(e) Pd

anonymous · Answer

The 1.70V should be -1.70 and the 0.560 should be -0.560
I am thinking Be2+, but will it always be lowest voltage?
