Question

what is the reduction potential for the half reaction at 25°C
Al3 + 3e- Al, if ( Al3+) = 0.10m and Eo = - 1.66v
Calculate the potential ( in volts) for the voltaic ( or galvanic) cell indicated at 25°C
Ga/Ga3+ (10-6)//Ag+ (10-4)/ Ag​

Answer 1

Explanation:

Problem Sheet 10. 1. ( a) ... (c). Sn2+(aq) → Sn4+(aq) + 2e-. E° = - 0.15 V. (reverse of reduction potential). MnO4 ... Reduction occurs in the Ag(s) | Ag+(s) half cell.
