Question

An electrochemical cell is set up as: Pt; H₂ (1atm)|HCl(0.1 M) || CH₃COOH (0.1 M)| H₂ (1atm); Pt. The e.m.f of this cell will not be zero, because
(a) the temperature is constant
(b) e.m.f depends on molarities of acids used
(c) acids used in two compartments are different
(d) pH of 0.1 M HCl and 0.1 M CH₃COOH is not same

Answer 1
