The constituent of air that turns limewater milky is Carbon Dioxide (CO2). Here's the step by step process:

1. When Carbon Dioxide (CO2) is passed through limewater (which is a common name for a diluted solution of calcium hydroxide), it reacts with the calcium hydroxide to form calcium carbonate and water.

2. Calcium carbonate is insoluble in water and is the substance that causes the milky appearance of the limewater.

3. The chemical reaction can be represented as follows:
Ca(OH)2 (aq) + CO2 (g) - CaCO3 (s) + H2O (l)

So, the answer to your question is Carbon Dioxide (CO2).
