Assertion: Sodium hydrogen carbonate is an acidic salt.
Reason: It is a salt produced by the neutralization reaction between a strong base (NaOH) and a weak acid `(H_(2)CO_(3))`.

Options

A. Both A and R are true and R is the correct explanation of A.
B. Both A and R are true but R is NOT the correct explanation of A.
C. A is true but R is false.
D. A is false and R is True.

Explanation

To solve the question, we need to analyze both the assertion and the reason given.

### Step 1: Understanding the Assertion
The assertion states that sodium hydrogen carbonate (NaHCO₃) is an acidic salt.

**Analysis**:
- Sodium hydrogen carbonate is indeed a salt, but to determine if it is an acidic salt, we need to consider the nature of the acid and base from which it is derived.

### Step 2: Understanding the Reason
The reason states that sodium hydrogen carbonate is produced by the neutralization reaction between a strong base (NaOH) and a weak acid (H₂CO₃).

**Analysis**:
- Sodium hydroxide (NaOH) is a strong base.
- Carbonic acid (H₂CO₃) is a weak acid.
- When a strong base reacts with a weak acid, the resulting salt (in this case, sodium hydrogen carbonate) tends to be basic in nature, not acidic.

### Step 3: Conclusion
- Since sodium hydrogen carbonate is formed from a strong base and a weak acid, it is classified as a basic salt, not an acidic salt. Therefore, the assertion is false.
- The reason provided is true as it correctly describes the neutralization reaction.

### Final Answer
- The assertion is false, and the reason is true. Therefore, the correct option is: **Assertion is false and reason is true.**
