Question

a) What is the potential of a redox electrode (relative to SHE) in which a platinum wire is immersed in a solution containing 0.075 M Sn⁺² and 0.310 M Sn⁺⁴? What would the potential of the indicating electrode if it was measured relative to an SCE electrode?

b) Calculate the potential of the following cell:

Pt ǀ Cr³⁺ (2.00x10^-4M) Cr²⁺ (1.50x10^-3 M)ǁ Pb²⁺(5.60x10^-2 M) ǀ Pb

Is the cell spontaneous as written?

Standard potentials needed for both sections:

Sn⁴⁺ + 2e- → Sn²⁺ E⁰ = 0.15 Volts

Cr³⁺ + e^- → Cr²⁺ E⁰ = -0.424 Volts

Pb²⁺ + 2e^- → Pb E⁰ = -0.13 Volts
