Question

The SI unit of electrochemical equivalent is ______.

Options

• J s^-1

• kg C^-1

• kg m s^-2

• kg m^-1 s^-2

Answer 1

The SI unit of electrochemical equivalent is kg C^-1.

Explanation:

The mass liberated in electrolysis by 1 coulomb is the electrochemical equivalent of a material. It may be computed using Faraday's second rule and the experimental knowledge that 96500 C liberates the equivalent weight in grammes of all compounds.

Electrochemical equivalent = `"Equivalent weight"/96500` gm per coulomb. Its unit Is kg C^-1.
