Question

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

Answer 1

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.
