In comparison of ferrous salts, ferric salts are:

Options

A. more stable
B. less stable
C. equally stable
D. None of these

Answer

To solve the question "In comparison of ferrous salts, ferric salts are:", we will analyze the stability of ferrous and ferric salts based on their electronic configurations.

### Step-by-Step Solution:

1. **Identify the oxidation states**:
- Ferrous salts contain iron in the +2 oxidation state (Fe²⁺).
- Ferric salts contain iron in the +3 oxidation state (Fe³⁺).

2. **Determine the electronic configurations**:
- For Fe²⁺ (ferrous ion): The electronic configuration is Argon (Ar) 3d⁶ 4s⁰.
- For Fe³⁺ (ferric ion): The electronic configuration is Argon (Ar) 3d⁵ 4s⁰.

3. **Analyze the stability based on electronic configuration**:
- The electronic configuration of Fe³⁺ (3d⁵) is half-filled. Half-filled and fully filled subshells are generally more stable due to lower energy and symmetry.
- The electronic configuration of Fe²⁺ (3d⁶) is not half-filled. It is less stable compared to the half-filled configuration of Fe³⁺.

4. **Conclusion**:
- Since ferric salts (Fe³⁺) have a more stable electronic configuration compared to ferrous salts (Fe²⁺), we conclude that ferric salts are more stable than ferrous salts.

### Final Answer:
In comparison to ferrous salts, ferric salts are **more stable**.
