Options

A. strong acid and strong base
B. strong acid and weak base
C. weak acid and weak base
D. strong base and weak acid

Explanation

To answer the question "Basic salts are formed by the neutralization of," we need to understand the concept of neutralization and the types of acids and bases involved in forming basic salts.

### Step-by-Step Solution:

1. **Understanding Neutralization**:
- Neutralization is a chemical reaction between an acid and a base that produces a salt and water. The general reaction can be represented as:
\[ \text{Acid} + \text{Base} \rightarrow \text{Salt} + \text{Water} \]

2. **Identifying Types of Acids and Bases**:
- Acids can be classified as strong or weak based on their ability to dissociate in water. Similarly, bases can also be classified as strong or weak.
- Strong acids (e.g., HCl, H2SO4) completely dissociate in solution, while weak acids (e.g., CH3COOH) only partially dissociate.
- Strong bases (e.g., NaOH, KOH) completely dissociate in solution, while weak bases (e.g., NH4OH) only partially dissociate.

3. **Formation of Basic Salts**:
- Basic salts are typically formed when a strong base reacts with a weak acid. This is because the resulting salt will have a tendency to hydrolyze in water, producing OH⁻ ions, which makes the solution basic.
- For example, when sodium hydroxide (a strong base) reacts with acetic acid (a weak acid), the product is sodium acetate, which is a basic salt:
\[ \text{NaOH} + \text{CH}_3\text{COOH} \rightarrow \text{CH}_3\text{COONa} + \text{H}_2\text{O} \]

4. **Conclusion**:
- Therefore, the correct answer to the question is that basic salts are formed by the neutralization of a **strong base and a weak acid**.

### Final Answer:
Basic salts are formed by the neutralization of a strong base and a weak acid.
