At `25^(@)C` the pH value of a solution is 6. The solution is

Options

A. Basic
B. Acidic
C. Neutral
D. Both (b) and (c)

Answer

To determine the nature of the solution given a pH value of 6 at 25°C, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding pH Scale**:
- The pH scale ranges from 0 to 14.
- A pH of 7 is considered neutral, values below 7 are acidic, and values above 7 are basic.

2. **Identify the pH Value**:
- Given pH = 6.

3. **Determine the Nature of the Solution**:
- Since 6 is less than 7, we can conclude that the solution is acidic.

4. **Calculate the Concentration of Hydrogen Ions**:
- The pH is defined as:
\[ \text{pH} = -\log[\text{H}^+] \]
- Rearranging this gives:
\[ [\text{H}^+] = 10^{-\text{pH}} \]
- Substituting the given pH value:
\[ [\text{H}^+] = 10^{-6} \, \text{M} \]

5. **Conclusion**:
- The solution is acidic because its pH is less than 7, and the concentration of hydrogen ions is \(10^{-6} \, \text{M}\).

### Final Answer:
The solution is acidic.
