An electrochemical cell is set up as: Pt; H 2 (1 atm)|HCl(0.1 M)|| C H 3 C O O H (0.1 M)| H 2 (1 atm); Pt. The e.m.f. of this cell will not be zero, because

Options

  1. Aacids used in two compartments are different
  2. Be.m.f. depends on molarities of acids used
  3. Cthe temperature is constant
  4. DpH of 0.1 M HCl and 0.1 M C H 3 C O O H is not same

Correct answer

D. pH of 0.1 M HCl and 0.1 M C H 3 C O O H is not same

Step-by-step solution

Since it is a concentration cell and the concentration of ions in two electrolyte solutions (HCl and C H 3 C O O H ) are different, therefore e.m.f. of this cell will not be zero.
