A neutralisation reaction is the reaction between an acid and a base to form salt and water.

General equation:

$$\text{Acid} + \text{Base} \rightarrow \text{Salt} + \text{Water}$$

Example:
$$\text{NaOH}(aq) + \text{HCl}(aq) \rightarrow \text{NaCl}(aq) + \text{H}_2\text{O}(l)$$

• 1 mark for the correct definition (acid + base → salt + water).
• 1 mark for the general/symbolic equation (or a correct example equation).
• Examiners look for the key words: acid, base, salt, and water. Missing any one of these loses the mark.
• A balanced example equation (like NaOH + HCl) can substitute for or support the general equation — include both to be safe.
