Options

A. atomic number of the cation
B. atomic number of the anion
C. equivalent weight of the electrolyte
D. speed of the cation

Answer

To answer the question regarding Faraday's laws of electrolysis, we will break down the concepts step by step.

### Step-by-Step Solution:

1. **Understanding Faraday's First Law of Electrolysis**:
- Faraday's first law states that the amount of substance deposited or liberated at an electrode during electrolysis is directly proportional to the quantity of electricity (charge) that passes through the electrolyte.
- Mathematically, this can be expressed as:
\[ m = Z \cdot I \cdot t \]
where:
- \( m \) is the mass of the substance deposited,
- \( Z \) is the electrochemical equivalent (which is equal to the equivalent weight of the substance divided by the Faraday constant, 96500 C/mol),
- \( I \) is the current in amperes,
- \( t \) is the time in seconds.

2. **Understanding Faraday's Second Law of Electrolysis**:
- Faraday's second law states that when the same quantity of electricity is passed through different electrolytes, the masses of the substances deposited or liberated at the electrodes are proportional to their equivalent weights.
- This means that if you have two different electrolytes, the mass of substance deposited from each will depend on their respective equivalent weights.

3. **Relationship to Equivalent Weight**:
- The equivalent weight of an electrolyte is crucial in determining how much of the substance will be deposited during electrolysis.
- The relationship can be summarized as:
\[ \text{Mass deposited} \propto \text{Equivalent weight} \]
- Thus, if we know the equivalent weight of an electrolyte, we can predict the mass of the substance that will be deposited when a certain amount of charge is passed through it.

4. **Conclusion**:
- Faraday's laws of electrolysis are fundamentally related to the equivalent weight of the electrolytes involved in the electrolysis process. The laws help us understand how much substance will be deposited based on the charge passed and the properties of the electrolyte.

### Final Answer:
Faraday's laws of electrolysis are related to the equivalent weight of the electrolyte.
