An electrochemical cell is shown below `Pt, H_(2)(1 "atm")|HCl(0.1 M)|

1.	An electrochemical cell is shown below `Pt, H_(2)(1 "atm")\|HCl(0.1 M)\|CH_(3)COOH(0.1 M)\|H_(2)(1 "atm")`, The emf of the cell will not be zero, becauseA. EMF depends on molarities of acids usedB. pH of 0.1 M HCl and 0.1 M `CH_(3)COOH` is sameC. the temperature is constantD. acids used in two compartments are different
Answer» Correct Answer - B (b)The EMF of the cell will not be zero because concentration of `H^(+)` ions in two electrolytic solution is different. Mean HCl is strong acid where, acetic acid is weak acid and gives different pH.
