Dolute nitric acid is generally not used for the preparation of original solution for the basic radicals because it :

Options

A. it is a reducing agent
B. it is an oxidising agent
C. forms insoluble nitrates
D. forms soluble nitrates

Explanation

To answer the question regarding why dilute nitric acid is generally not used for the preparation of original solutions for basic radicals, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Dilute Nitric Acid**:
- Dilute nitric acid is represented by the chemical formula HNO3. It is important to recognize its properties, particularly its behavior in chemical reactions.

2. **Identifying the Nature of Nitric Acid**:
- Nitric acid (HNO3) is known to be an oxidizing agent. This means that it has the ability to gain electrons from other substances during a chemical reaction.

3. **Effect of Oxidizing Agents on Cations**:
- When an oxidizing agent is present, it can increase the oxidation state of cations (positively charged ions). For example, if a cation has a low oxidation state, the oxidizing agent can convert it into a cation with a higher oxidation state by removing electrons.

4. **Implications for Basic Radicals**:
- Basic radicals are typically cations that are used in qualitative analysis to identify different ions in a solution. If these cations are oxidized (i.e., their oxidation state is increased) by the nitric acid, it can lead to the formation of different compounds that may not be easily recognizable or may not precipitate as expected.

5. **Conclusion**:
- Due to the oxidizing nature of dilute nitric acid, it is not suitable for preparing original solutions for basic radicals, as it can alter the cations present, making them unidentifiable. Therefore, the correct answer to the question is that dilute nitric acid is generally not used because it is an oxidizing agent.

### Final Answer:
Dilute nitric acid is generally not used for the preparation of original solutions for basic radicals because it is an oxidizing agent.
