STATEMENT 2 One faraday deposits one mole of substance

Options

B. Statement 1 is true Statement 2 is ture Statement 2 is NOT a correct explantion for Statement 8
C. Statement 1 is true statement 2 is ture
D. Statement 1 is false Statement 2 is true

Answer

To analyze the given statements, let's break them down step by step.

### Step 1: Understanding the First Statement
**Statement 1:** "One coulomb of electric charge deposits the weight that is equal to the electrochemical equivalent of a substance."

- **Electrochemical Equivalent (Z):** The electrochemical equivalent of a substance is defined as the mass of the substance that is deposited or liberated at an electrode during electrolysis when one coulomb of electric charge passes through the electrolyte.
- **Conclusion:** Therefore, this statement is true. One coulomb of electric charge indeed deposits a weight equal to the electrochemical equivalent of the substance.

### Step 2: Understanding the Second Statement
**Statement 2:** "One faraday deposits one mole of substance."

- **Faraday's Law of Electrolysis:** According to Faraday's laws, the amount of substance deposited at an electrode is proportional to the quantity of electricity passed through the electrolyte. One faraday (F) is defined as the charge of one mole of electrons, which is approximately 96485 coulombs.
- **Molecular Weight and Equivalent Weight:** The relationship can be expressed as:
\[ \text{Weight} = \frac{\text{Molecular Weight}}{n} \times \text{Charge (in Faradays)} \]
where \( n \) is the number of moles of electrons transferred (valency).
- **Conclusion:** The statement "One faraday deposits one mole of substance" is incorrect. It actually deposits one equivalent of the substance, which may not necessarily be one mole unless the valency (n) is 1.

### Final Conclusion
- **Statement 1 is True.**
- **Statement 2 is False.**

### Answer: Option C (Statement 1 is true, Statement 2 is false)
