The unit of electrochemical equivalent is

A

gm `"ampere"^(-1)`

B

gm/coulomb

C

gm-ampere

D

coulomb/gram.

Text Solution

Verified by Experts

The correct Answer is:
B
W=Z, Q
W=weight of substance deposited
Q=quantity of electricity passed
Z=electochemical equivalent
` Z=(W)/(Q)=(gm)/("coulomb")=gm`/coulomb.
