The unit of electrochemical equivalent (Z) in Class 12 Physics or Chemistry is:
kg/C (kilogram per coulomb)
But sometimes, in smaller units, it's also expressed as:
g/C (gram per coulomb)
---
What is Electrochemical Equivalent?
The electrochemical equivalent (Z) of a substance is the mass of the substance deposited or liberated when 1 coulomb of electric charge passes through its solution.
---
Formula:
\[
Z = \frac{m}{Q}
\]
Where:
---
Example:
If 1 coulomb of charge deposits 1.118 mg (0.001118 g) of silver, then:
\[
Z = \frac{0.001118\ g}{1\ C} = 0.001118\ g/C
\]

Let me know if you’d like a simple diagram or explanation using Faraday’s laws too!

Formula:
\[

\]
Where:
- \( Z \) = Electrochemical equivalent
- \( m \) = Mass deposited (in kg or g)
- \( Q \) = Charge (in coulombs)

Example:
If 1 coulomb of charge deposits 1.118 mg (0.001118 g) of silver, then:
\[
Z = \frac{0.001118\ g}{1\ C} = 0.001118\ g/C
