AI-generated practice question — model-generated for extra practice, not a previous-year CBSE board question.

Q1. [1] straightforward initial-understanding
Write the chemical equation for the reaction between NaOH and HCl.

Model Answer

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

Source: Chapter 2, Section 2.1.4

Explanation

This is a neutralisation reaction — acid + base → salt + water. Examiners expect the balanced equation with state symbols. NaCl (common salt) and water are the products. One mark is awarded for the correct balanced equation; state symbols add precision but the equation itself is the key requirement.
