……. are the products obtained when bleaching powder reacts with dilute sulphuric acid.

The products obtained when bleaching powder reacts with dilute sulphuric acid are chlorine gas, water, and calcium sulphate. Here's the step by step reaction:

1. Write down the chemical formula for bleaching powder, which is CaOCl2.

2. Write down the chemical formula for dilute sulphuric acid, which is H2SO4.

3. When these two react, they form chlorine gas (Cl2), water (H2O), and calcium sulphate (CaSO4).

So, the balanced chemical equation for this reaction is:

CaOCl2 + H2SO4 → Cl2 + H2O + CaSO4

This means that for every molecule of bleaching powder and sulphuric acid that react, one molecule of chlorine gas, one molecule of water, and one molecule of calcium sulphate are produced.
