Answer 2

When we exhale into lime water containing glass, it turns milky.

• The chemical name of lime is calcium hydroxide.
• When we exhale, we let out carbon dioxide.
• Carbon dioxide reacts with calcium hydroxide to produce calcium carbonate.
• Calcium carbonate is an insoluble precipitate that is white in color.
• It is this precipitate that gives the lime water a milky appearance.
• This is a procedure commonly used in the detection of carbon dioxide gas.
