Calcium hydroxide+carbon dioxide------calcium Carbonate+water

Answer»

Hey dear mate Here is ur answer :-

Carbon dioxide reacts with LIMEWATER (a solution of CALCIUM hydroxide, CA(OH)2), to form a white precipitate (appears milky) of calcium carbonate, CaCO3.

Adding more carbon dioxide RESULTS in the precipitate dissolving to form a colourless solution of calcium hydrogencarbonate.

Ca(OH)2(aq) + CO2(g) → CaCO3(s) + H2O(l)

CaCO3(s) + CO2(g) + H2O(l) → Ca(HCO3)2(aq)

This is used as a test for carbon dioxide.

When carbon dioxide is bubbled through limewater the limewater changes from colourless to milky.

Hope it helps u ☺❤
