Select the incorrect statement.

Options

A. `NaOH` can be stored in a vessel made of aluminium
B. `HNO_(3)` can be stored in a vessel made of Be/Aluminium alloy
C. `HF` can be stored in a vessel coated of wax
D. `HF` attacks glass

Answer

To solve the given question, we need to analyze each statement provided and determine which one is incorrect regarding the storage of various chemicals.

### Step-by-Step Solution:

1. **Analyze Option A:**
- Statement: Sodium Hydroxide (NaOH) can be stored in a vessel made of Aluminium.
- **Analysis:** Sodium Hydroxide is known to react with Aluminium, producing Sodium Aluminate and Hydrogen gas. Therefore, storing NaOH in an Aluminium vessel is not safe or advisable as it will lead to a reaction and the formation of Sodium Aluminate.
- **Conclusion:** This statement is incorrect.

2. **Analyze Option B:**
- Statement: Nitric Acid (HNO3) can be stored in a vessel made of Beryllium Aluminium Alloy.
- **Analysis:** Nitric Acid does not react with Beryllium Aluminium Alloy, making it safe for storage. Therefore, this statement is correct.
- **Conclusion:** This statement is correct.

3. **Analyze Option C:**
- Statement: Hydrofluoric Acid (HF) can be stored in a vessel coated with wax.
- **Analysis:** Hydrofluoric Acid is unreactive towards wax, which makes it suitable for storage in a wax-coated vessel. Therefore, this statement is correct.
- **Conclusion:** This statement is correct.

4. **Analyze Option D:**
- Statement: HF attacks glass.
- **Analysis:** Hydrofluoric Acid reacts with the silica (SiO2) present in glass, forming hydrofluorosilicic acid. This means that storing HF in glass is not advisable as it will corrode the glass. Therefore, this statement is correct.
- **Conclusion:** This statement is correct.

### Final Conclusion:
- The incorrect statement among the options is **Option A**: Sodium Hydroxide cannot be stored in a vessel made of Aluminium due to its reactivity.
