In Chemistry (Class 12), **ECE** refers to **Electrochemical Equivalent**. It is a concept used in the study of electrochemistry, specifically in understanding how much substance is deposited or dissolved during electrolysis when a certain amount of electric charge passes through the electrolyte.
### Formula for ECE:
The electrochemical equivalent (Z) can be calculated using the formula:
\[
Z = \frac{M}{F}
\]
Where:
- **M** is the molar mass of the substance being deposited or dissolved (in grams).
- **F** is the Faraday constant (approximately 96,500 C/mol, which is the charge of 1 mole of electrons).
It helps to calculate the mass of a substance deposited or liberated at the electrodes during electrolysis based on the quantity of electric charge that flows through the system.
This concept is important for understanding processes like electroplating or electrorefining in industrial chemistry.
