The SI unit of electrochemical equivalent is
Options
- AJ s - 1
- BK g C - 1
- CK g m s - 2
- DK g m - 1 s - 2
Correct answer
B. K g C - 1
Step-by-step solution
The electrochemical equivalent of a substance is the mass liberated in electrolysis by 1 coulomb. It can be calculated by assuming by 1 coulomb Faraday’s second law and using the experimental fact that the equivalent weight in gams of all substances is liberate by 96500 C. Electrochemical equivalent = E q u i v a l e n t w e i g h t 96500 Gm per coulomb. Its unit is k g C - 1 .
