Q. Standard reduction potentials for, $ L{{i}^{+}}/Li; $ $ Z{{n}^{2+}}/Zn; $ $ {{H}^{+}}/{{H}_{2}} $ and $ A{{g}^{+}}/Ag $ are $ -3.05, $ $ -0.762, $ $ 0.00 $ and $ +0.80 $ V respectively. Which of the following has highest reducing capacity?

Solution:

More negative is the value of standard reduction potential, higher will be the reducing power. $ \therefore $ $ L{{i}^{2+}}/Li $ has the highest reducing power.
