This section contains Assertion and Reason type questions each question has 4 choices (1)(2)(3) and (4) out of which only one is correct
Assertion: Boric acid as a dilute aqueous solution is used as a weak antiseptic for eyes
Reason:Boric acid is a dibasic acid

Options

A. Both A and R are correct ,R is the correct explanation of A
B. Both A and R are correct,R is not the correct explanation of A
C. A is correct ,R is incorrect
D. R is correct,A is incorrect

Answer

To solve the Assertion and Reason type question, we need to analyze both the assertion and the reason provided.

### Step 1: Analyze the Assertion
The assertion states that "Boric acid as a dilute aqueous solution is used as a weak antiseptic for eyes."

- Boric acid (H₃BO₃) is indeed used in dilute solutions as an antiseptic. It has mild antibacterial properties and is often used in eye washes and solutions for treating minor eye irritations. Therefore, the assertion is **True**.

### Step 2: Analyze the Reason
The reason states that "Boric acid is a dibasic acid."

- A dibasic acid is defined as an acid that can donate two protons (H⁺ ions) per molecule in a reaction. However, boric acid does not behave as a traditional acid that donates protons; instead, it acts as a Lewis acid by accepting hydroxide ions (OH⁻) from water. In fact, boric acid is classified as a **monobasic acid** because it can only accept one hydroxide ion in solution. Therefore, the reason is **False**.

### Step 3: Conclusion
Since the assertion is true and the reason is false, we conclude that the correct answer is:

- **Option (1)**: Assertion is true, Reason is false.

### Summary of Steps:
1. **Assertion**: Confirmed true as boric acid is used as a weak antiseptic.
2. **Reason**: Confirmed false as boric acid is not dibasic but monobasic.
