An electrochemical cell is set up as follows Pg(H_(2),1" atm")//0.1M" "HCl ||0.1M" acetic acid "//(H_(2),1" atm")Pt E.M.F. of this cell will not be zero because

Answer»

The pH of 0.1 M HCl and 0.1 M acetic ACID is not the same
Acids used in two COMPARTMENTS are different
E.M.F of a CELL depends on the MOLARITIES of acids used
The temperature is constant

Solution :The pH of 0.1 M HCl and 0.1 M acetic acid is not the same, because HCl is a strong acid to its pH is less and `CH_(3)COOH` is a weak acid, so its pH is more.
