TEST FOR CARBON DIOXIDE: LIMEWATER TURNS MILKY<br />
Calcium Carbonate Reacts With Hydrochloric Acid<br />
Calcium carbonate reacts with hydrochloric acid releasing CO2(g) which is bubbled through limewater, a saturated solution of calcium hydroxide, the limewater turns milky as calcium carbonate precipitates.  CO2(g) + Ca 2+ + 2OH- -> CaCO3(s) + H2O(l)
