The `pH` of an acidic buffer solution & a basic buffer solution at `25^(@)C` is :

Options

A. `gt7,lt7`
B. `lt7,gt7`
C. `=7,=7`
D. Dependent upon `K_(a)`&K_(b)` of acid & base respectively.

Explanation

To determine the pH of an acidic buffer solution and a basic buffer solution at 25°C, we can follow these steps:

### Step 1: Understand the Definition of Buffer Solutions
Buffer solutions are solutions that resist changes in pH when small amounts of acid or base are added. There are two types of buffer solutions: acidic buffers and basic buffers.

### Step 2: pH of Acidic Buffer
For an acidic buffer solution, the pH can be calculated using the Henderson-Hasselbalch equation:
\[ \text{pH} = \text{pK}_a + \log\left(\frac{[\text{Salt}]}{[\text{Acid}]}\right) \]
