Question

Waht happens when CO2 is passed in excess through lime?

Answer 1

If you pass excess CO2 through lime-water, the CaCO3 reacts with the excess CO2 and water to form calcium hydrogen carbonate or calcium bicarbonate. Calcium bicarbonate is soluble in water and thus the milkiness dissolves in water.

Answer 2

Answer:

listen dude

Explanation:

when carbon dioxide is passed through lime water, it turns milky or turbid due to the formation of calcium carbonate which is insoluble in water. however if excess carbon dioxide is allowed to pass, the turbidity disappears due to the formation of calcium bicarbonate which is soluble in water.
