Mark 'T' if the statement is true and 'F' if it is false:
Sodium hydroxide and hydrochloric acid neutralise each other and form salt and water. (T/F)

Answer

To determine whether the statement "Sodium hydroxide and hydrochloric acid neutralise each other and form salt and water" is true or false, we can follow these steps:

### Step 1: Identify the substances involved
- Sodium hydroxide (NaOH) is a base.
- Hydrochloric acid (HCl) is an acid.

### Step 2: Understand the concept of neutralization
- A neutralization reaction occurs when an acid reacts with a base to produce salt and water.

### Step 3: Write the neutralization reaction
- The reaction between sodium hydroxide and hydrochloric acid can be represented as:
\[ \text{NaOH} + \text{HCl} \rightarrow \text{NaCl} + \text{H}_2\text{O} \]
- Here, sodium chloride (NaCl) is the salt formed, and water (H₂O) is also produced.

### Step 4: Analyze the products of the reaction
- From the reaction, we see that the products are indeed salt (NaCl) and water (H₂O).

### Conclusion
- Since sodium hydroxide and hydrochloric acid react to form salt and water, the statement is **True (T)**.

### Final Answer
- Mark the statement as **T** (True).
