Question

The mass of the substance deposited by 1 faraday of electricity is equal to 11 grams. The value of electrochemical equivalent is:

• A. $11$
• B. $11\times 96500$
• C. $\frac{11}{96500}$
• D. data insufficient

Answer 1

The correct option is C $\frac{11}{96500}$

Electrochemical equivalent $\left(Z\right)$ is the mass of the substance deposited by one coulomb. 1 faraday is 96500 coulombs.

$ct=96500$ C.

$m=Z\times c\times t$ . Thus, mass deposited is $\frac{11}{96500}$
