Question

state your observation when carbon dioxide is bubbled into lime water​

Answer 1

Answer:

We are reacting lime water with excess carbon dioxide (CO2). First, let's define lime water. It is a solution of calcium hydroxide (Ca(OH)2) in water. Calcium hydroxide is partially soluble in water and makes water alkaline, or basic on the pH scale. If CO2 is bubbled through lime water it reacts with the calcium hydroxide to produce calcium carbonate. The chemical reaction is shown below.

Ca(OH)2 + CO2 --> CaCO3 + H2O

Calcium carbonate is very insoluble in water so it will precipitate from solution as if forms. 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

Answer:

if carbon dioxide is bubbled through lime water it reacts with the calcium hydroxide to produce calcium carbonate . so , if CO2 gas is bubbled through the clear , colourless solution of lime water , the water will become hazy and milky coloured as the calcium carbonate precipitate as a white solid suspended in the water ...
