Separation of basic radicals is based on (a) ____ and (b) ____.

Answer

To answer the question regarding the separation of basic radicals, we can break down the solution into clear steps:

### Step-by-Step Solution:

1. **Understanding Basic Radicals**: Basic radicals are positively charged ions (cations) that can be separated from a mixture in qualitative analysis.

2. **Identifying Factors for Separation**: The separation of basic radicals is based on two main factors:
- **Common Ion Effect**
- **Solubility Product Values (Ksp)**

3. **Explaining the Common Ion Effect**:
- When a strong electrolyte that contains an ion common to a weak electrolyte is added to a solution, the ionization of the weak electrolyte is suppressed.
- This suppression affects the precipitation of the basic radicals, allowing for their separation.

4. **Explaining Solubility Product Values**:
- Different salts have different solubility product values (Ksp).
- When salts differ widely in their Ksp values, they can be separated by precipitation because they will precipitate out of solution at different concentrations.

5. **Final Answer**: Therefore, the separation of basic radicals is based on:
- (a) Common Ion Effect
- (b) Solubility Product Values
