Question

What happen when co2 gas passed throuugh the lime water ?In small amount ?In excess?

Answer 1

Explanation:

The chemical reaction is shown below. We are reacting lime water with excess carbon dioxide (CO2). ... So if carbon dioxide gas is bubbled through a clear, colorless solution of lime water, the water will become hazy and milky colored as the calcium carbonate precipitates as a white solid suspended in the water.

Answer 2

HI friend

When CO2 is passed through lime-water, it turns milky due to the formation of an insoluble precipitate of Calcium Carbonate. ... The CaCO3 precipitate causes the milkiness. 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
