An electrochemical cell is set up as follows `Pg(H_(2),1" atm")//0.1M"

1.	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 becauseA. The pH of 0.1 M HCl and 0.1 M acetic acid is not the sameB. Acids used in two compartments are differentC. E.M.F of a cell depends on the molarities of acids usedD. The temperature is constant
Answer» Correct Answer - A 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.
