qawhen carbon dioxide is passed in lime water for a long time the lime water turns milky and then again turns into colourless solution to the formation of a soluble precipitate called calcium bicarbonate

Answer 2

Answer:

↤↤↤ Ⓗⓔⓛⓛⓞ ↦↦↦

Explanation:

When CO2 is passed through lime water, it turns

milky due to the formation of calcium carbonate which

is insoluble in water.

(limewater)Ca(OH)2+CO2⟶(milkiness)CaCO3+H2O

However, when excess of CO2 is passed through this

solution, the milkiness disappears. This is due to the

formation of calcium bicarbonate which is colorless and

soluble in water.

(milkiness)CaCO3+H2O+(excess)CO2⟶(water soluble)
