Question

What is the effect of exhaled air on lime water
Very short answer​

Answer 1

As exhaled air has more CO2 therefore it turns lime water milky that is white in colour

Answer 2

HERE YOU GO,

SHORT AND PRECISE

Exhaled air is CO2(Carbon Dioxide)

Lime Water is Ca(OH)2 (Calcium Hydroxide)

Therefore, when Calcium Hydroxide combines with Carbon Dioxide it leaves a milky white precipitate.This precipitate is called CaCO​3.

This can be showed in the form of an equation.

Ca(OH)2 + CO2 ➜ CaCO3 + H2
