The standard potential of the cell Ag(s) |AgCl(s) m Cl^-(aq) |Cu²⁺(aq) |Cu(s)
Is +0.12 V at 25^$\circ$C.If the standard potential of the Cu²⁺/Cu couple is +0.34 V,calculate the standard potential of the AgCl/Ag,Cl^-couple.

Question

Quizplus · Accepted Answer

The standard potential of the cell is the difference between the potentials of the cathode and anode. Given the cell potential is +0.12 V and the Cu²⁺/Cu couple is +0.34 V, the AgCl/Ag, Cl⁻ couple potential is calculated as +0.12 V - (+0.34 V) = -0.22 V. However, since the AgCl/Ag, Cl⁻ couple is the anode, its potential is the negative of this value, which is +0.22 V.
