Question

What happens when carbon dioxide gas is passed through lime water ? Write a word equation for this process.

Answer 1

Answer:

The lime water turns milky

Explanation:

Answer 2

When carbon dioxide gas is passed through lime water the lime water turns milky.

• The chemical formula of lime water is $Ca(OH)_2$.
• When carbon dioxide reacts with lime water or calcium hydroxide it turns milky due to the formation of calcium carbonate along with water.
• The reaction is as follows-
• $CO_2+Ca(OH)_2\rightarrow CaCO_3+H_2O$.
• Thus one mole of carbon dioxide reacts with one mole of calcium hydroxide to form one mole of calcium carbonate along with one mole of water.
