Which of the following is not correct?
- A Aqueous solution of \(\mathrm{NaCl}\) 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
Answer & Solution
Correct Answer
(B) The units of electrochemical equivalent are g-Coulomb
Step-by-step Solution
Detailed explanation
The unit of electrochemical equivalent \((\mathrm{Z})\) is g/Coulomb. \(\begin{aligned} & w & =z . i . t \\ \therefore \quad & z & =\frac{w}{i . t} \mathrm{~g} / \text { Coulomb } \end{aligned}\)
