Question: An electrochemical cell is set up as follows $Pt({{H}_{2}},\,1\,atm)/0.1\,M\,HCl||0.1M\,\text{acetic acid/(}{{H}_{2}},\,1\,atm)Pt$ emf of this cell will not be zero because



1) The $pH$ of 0.1 M $HCl$ and 0.1 M acetic acid is not the same
2) Acids used in two compartments are different
3) $emf$ of a cell depends on the molarities of acids used
4) The temperature is constant
Solution: Explanation: No Explanation
Electrode potential Ecell Nernst equation and ECS
