Carbon dioxide turns lime water milky.
Carbon dioxide passed into limewater gives a milky solution. This is due to the insoluble suspension of calcium carbonate formed:
Ca(OH)2(aq)+CO2(g)→CaCO3(s)+H2O(l)
Statement 1- Lime water turns milky when air is passed through the solution.
Statement 2- Air contains carbon dioxide which turns lime water milky.
