The oxidizing character i.e. acceptance of electrons
increases with the reduction potential.

According to electrochemical series.

An electrochemical cell is set up as follows
Pt(H₂ , 1atm) / 0.1M HCl
|| 0.1 M acetic acid /( H₂ , 1atm ) Pt
E.M.F. of this cell will not be zero because

1The pH of 0.1 M HCl and 0.1 M acetic acid is not the same
2Acids used in two compartments are different
3E.M.F. of a cell depends on the molarities of acids used
4The temperature is constant

The pH of 0.1 M HCl and 0.1 M acetic acid is not the
same, because HCl is a strong acid so its pH is less and
CH₃COOH is a weak acid, so its pH is more.
