MHT CET Chemistry question
The half cell reaction of the cell used in hearing aids are Zn → Zn + 2e ( = +0.76 V) AgO + HO + 2e → 2Ag + 2OH ( = +0.34 V) of the cell is
Answer: (C)
Solution
The first potential is an oxidation potential and the second a reduction potential, so E = 0.76 + 0.34 = 1.10 V;
