Chapter 13, Problem 10RAT

What element is oxidized in this equation and what element is reduced?

${\text{Sn}}^{\text{2+}}\text{+2Ag}\to \text{Sn}+2{\text{Ag}}^{\text{+}}$

(a) The tin ion, ${\text{Sn}}^{\text{2+}}$, is oxidized; the silver, $\text{Ag}$, is reduced.

(b) The tin ion, ${\text{Sn}}^{\text{2+}}$, is reduced; the silver, $\text{Ag}$, is oxidized.

(c) Both the tin ion, ${\text{Sn}}^{\text{2+}}$, and the silver, $\text{Ag}$, are reduced.

(d) Both the tin ion, ${\text{Sn}}^{\text{2+}}$, and the silver, $\text{Ag}$, are oxidized.
