Question

What is the shorthand notation (i.e., line notation) that best represents a complete electrochemical cell for the following galvanic cell reaction?
Sn^2+ (aq) + F2 (g) → Sn^3+ (aq) + 2F^− (aq)
O Pt(s) | Sn^2+ (aq), Sn^3+ (aq) || F2 (g) F^-(aq)| C(s)
O F2(g)|F^- (aq) || Sn^2+(aq) | Sn^3+ (aq)
O Sn(s) | Sn^2+(aq) || Sn^4+ (aq) F2 (g)|F^- (aq)| C(s)
O Sn^2+ (aq) | Sn^3+ (aq) || F2 (g)|F^- (aq)
O Pt(s) | Sn^4+ (aq), Sn2^+ (aq), F2 (g) || F^- (aq) | C(s)

Answer 1

Answer:

Sn^2+(aq)/Sn^3+(aq)//F2(g)/2F-(aq)

Explanation:

In writing the shorthand notation for an electrochemical cell, the oxidation half cell is shown on the left hand side and the reduction half cell is shown on the right hand side. The oxidation half equation reflects electron loss while the reduction half equation reflects electron gain.
