Consider the following statements :
In the chemical reaction
(1) Manganese ion is oxidised (2) Manganese ion is reduced
(3) Chloride ion is oxidised (4) Chloride ion is reduced
which of theses statements are correct

Options

A. 1 and 3
B. 1 and 4
C. 2 and 3
D. 2 and 4

Explanation

To determine which statements about the manganese ion (Mn) and chloride ion (Cl) are correct, we need to analyze the oxidation states of these ions and understand the concepts of oxidation and reduction.

### Step-by-Step Solution:

1. **Identify the oxidation states**:
- The manganese ion (Mn) typically has oxidation states ranging from +2 to +7. In its +2 state, it is in a reduced form.
- The chloride ion (Cl) typically has an oxidation state of -1.

2. **Determine the nature of the reaction**:
- Oxidation is defined as the loss of electrons or an increase in oxidation state.
- Reduction is defined as the gain of electrons or a decrease in oxidation state.

3. **Analyze the statements**:
- **Statement (1)**: "Manganese ion is oxidized" - This statement is incorrect if Mn is in its +2 state, as it is in a reduced form.
- **Statement (2)**: "Manganese ion is reduced" - This statement is correct if Mn is in its +2 state, as it is already in a lower oxidation state.
- **Statement (3)**: "Chloride ion is oxidized" - This statement is incorrect because Cl is in its -1 state, which is a reduced form.
- **Statement (4)**: "Chloride ion is reduced" - This statement is also incorrect since Cl is already in a reduced state (-1).

4. **Conclusion**:
- The only correct statement is (2): "Manganese ion is reduced".

### Summary of Correct Statements:
- Correct Statement: (2) Manganese ion is reduced.
- Incorrect Statements: (1), (3), and (4).
