An electrichemical cell is set up as :Pt; H2 (1atm)/ HCl (0.1 M) // CH – InterviewSolution

1.	An electrichemical cell is set up as :Pt; H2 (1atm)/ HCl (0.1 M) // CH3COOH (0.1M)/ H2 (1atm) ;Pt. The e.m.f of this cell will not be zero, because(1) Acids used in two compartments are different(2) e.m.f depends on molarities of acids used(3) The temperature is constant(4) pH of 0.1 M HCl & 0.1 M CH3COOH is not same
