Q. Which of the following is not correct?
A) Aqueous solution of NaCl is an electrolyte.
B) The units of electrochemical equivalent are g-coulomb.
C) In the Nernst equation, $n$ represents the number of electrons transferred in the electrode reaction.
D) Standard reduction potential of hydrogen electrode is zero volt.
Explanation
(b)
The unit of electrochemical equivalent (Z) is g/C.
$w\ = \ Z.i.t$
$\therefore\ \ \ \ \ \ Z\ \ = \ \frac{w}{i.t}\ g/C$
