Question

In the cell Pt(s) | H₂(g, 1bar) | HCl(aq) | AgCl(s) | Ag(s) | Pt(s) the cell potential is 0.92 V when a 10^–6 molal HCl solution is used. The standard electrode potential of (AgCl / Ag,Cl^–) electrode is :

(1) 0.40 V 

(2) 0.76 V 

(3) 0.20 V 

(4) 0.94

Answer 1

The correct option is (3) 0.20 V.

Why n=1 it shoul be 2

---

n = valence factor of that compound taken. As a given above question valence factor of Cl and Ag is 2 but due to balancing of reactions Coefficient is 1.otherwise 2 is also correct
