Explanation:

When carbon dioxide, CO2, enters the limewater, the limewater becomes cloudy. When you exhale into the bottle, the limewater will turn cloudy.

The lime water turns from colourless to milky.

This is because the exhaled air contains about 4% CO2.

CO2 reacts with lime water to form a milky coloured compound.

Ca(OH)2(aq) + CO2(g) → CaCO3(s) + H2O(l)

If excess CO2 is added, the following reaction takes place:

CaCO3(s) + H2O(l) + CO2(g) → Ca(HCO3)2(aq)

The milkiness disappears since calcium bicarbonate is water-soluble.
