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 question of identifying the incorrect statement regarding the storage of various chemicals, we will analyze each option step by step.

### Step-by-Step Solution:

1. **Analyze Option 1: NaOH can be stored in a vessel made of aluminum.**
- Sodium hydroxide (NaOH) is a strong base that reacts with aluminum. When NaOH comes into contact with aluminum, it can produce hydrogen gas, which is flammable and potentially explosive. Therefore, it is incorrect to state that NaOH can be stored in aluminum vessels.
- **Conclusion:** This statement is incorrect.

2. **Analyze Option 2: HNO3 can be stored in a vessel made of BE (beryllium) aluminum alloy.**
- Nitric acid (HNO3) is compatible with certain metals, including beryllium aluminum alloys. These materials can withstand the corrosive nature of nitric acid without significant reaction.
- **Conclusion:** This statement is correct.

3. **Analyze Option 3: HF can be stored in a vessel coated with HF attack glass.**
- Hydrofluoric acid (HF) is known to attack glass due to its ability to react with silica. Therefore, it cannot be stored in glass vessels, including those that are coated with glass.
- **Conclusion:** This statement is incorrect.

4. **Analyze Option 4: HF can be stored in vessels made of wax.**
- HF can indeed be stored in vessels made of wax, as wax does not react with hydrofluoric acid. This makes it a suitable material for storing HF.
- **Conclusion:** This statement is correct.

### Final Answer:
The incorrect statement is **Option 1: NaOH can be stored in a vessel made of aluminum.**
