Question

Electron chemical equivalent of a substance is $0.0006$; its e wt. is?

• A. $57.9$
• B. $28.95$
• C. $115.8$
• D. Cannot be calculated

Answer 1

Answer: (A)

$57.9$

According to Faraday's law of electrolysis, the equivalent weight is 96500 times more than the electrochemical equivalent of the substance.

If electrochemical equivalent of substance is 0.0006 , then its equivalent weight is obtained by multiplying it with 96500.

i.e. $96500\times 0.0006=57.9g$

Thus, equivalent weight of given substance = 57.9 g
