Model Answer
A reaction in which an acid and a base react with each other to form salt and water is called a neutralisation reaction. Heat is also released in this process.
General equation:
$$\text{Acid} + \text{Base} \rightarrow \text{Salt} + \text{Water}$$
Example: NaOH + HCl → NaCl + H₂O

Explanation
- The examiner expects the definition (acid + base → salt + water) and the general equation — both are needed for full 2 marks.
- Mentioning heat release is a good addition but not compulsory for this mark allocation.
- A concrete example (like NaOH + HCl) strengthens the answer but keep it brief since this is only 2 marks.
- Do not write a long paragraph — one definition sentence + the equation is sufficient.
