How much volume of `0.2` M solution of acetic acid shouls be added to 100 ml of `0.2 ` M solution of sodium acetate to prepare a buffer solution of pH `5.00` ? `pK_(a)` for acid is ` 4.74 `

Explanation

To solve the problem of how much volume of 0.2 M solution of acetic acid should be added to 100 ml of 0.2 M solution of sodium acetate to prepare a buffer solution of pH 5.00, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Given Values**:
- pH of the buffer solution = 5.00
- pKa of acetic acid = 4.74
- Molarity of sodium acetate (salt) = 0.2 M
