The nature of 0.1 M solution of sodium bisulphate is

Options

A. Acidic
B. Alkaline
C. Neutral
D. Amphoteric

Answer

To determine the nature of a 0.1 M solution of sodium bisulphate (NaHSO4), we can follow these steps:

### Step 1: Identify the compound
Sodium bisulphate is represented by the formula NaHSO4. It consists of sodium ions (Na⁺) and bisulphate ions (HSO4⁻).

### Step 2: Dissociation in water
When sodium bisulphate is dissolved in water, it dissociates into its constituent ions:
\[ \text{NaHSO}_4 \rightarrow \text{Na}^+ + \text{HSO}_4^- \]

### Step 3: Analyze the bisulphate ion
The bisulphate ion (HSO4⁻) can further dissociate in water:
\[ \text{HSO}_4^- \rightleftharpoons \text{H}^+ + \text{SO}_4^{2-} \]

This dissociation releases hydrogen ions (H⁺) into the solution.

### Step 4: Determine the nature of the solution
The presence of H⁺ ions in the solution indicates that the solution is acidic.

### Conclusion
Therefore, the nature of a 0.1 M solution of sodium bisulphate (NaHSO4) is **acidic**.
