Who gave the law of electrolysis?

Options

A. Berglus
B. Faradey
C. Kohlrausch
D. Haber

Answer

To answer the question "Who gave the law of electrolysis?", we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Electrolysis**:
- Electrolysis is a chemical process that uses electrical energy to drive a non-spontaneous reaction. It involves the movement of ions in an electrolyte towards electrodes where they undergo reduction or oxidation.

2. **Identifying the Laws of Electrolysis**:
- The laws that describe the relationship between the amount of substance deposited or liberated at an electrode during electrolysis and the quantity of electricity used are known as the laws of electrolysis.

3. **Recognizing the Scientist**:
- The scientist who formulated these laws is Michael Faraday. He is known for his contributions to the field of electrochemistry.

4. **Stating Faraday's Laws**:
- Faraday established two fundamental laws of electrolysis:
- **First Law of Electrolysis**: The mass of a substance deposited or liberated at an electrode during electrolysis is directly proportional to the quantity of electricity passed through the electrolyte.
- **Second Law of Electrolysis**: The mass of different substances deposited or liberated by the same quantity of electricity is proportional to their equivalent weights.

5. **Historical Context**:
- Michael Faraday introduced these laws in the year 1833, marking a significant advancement in the understanding of electrochemical processes.

### Conclusion:
The law of electrolysis was given by **Michael Faraday**.
