when sulphur dioxide gas is passed through lime water it turns milky but the milkiness disappears when sulphur dioxide is passed for a longer time.Why?
Asked by mahimachaki chaki | 22 Nov, 2013, 08:51: PM
Expert Answer
SO2 turns lime water milky due to formation of calcium sulphite.
Ca(OH)2 + SO2 → CaSO3 + H2O
Milkiness disappears due to formation of calcium hydrogen sulphite which is soluble in water.
CaSO3 + SO2 + H2O → Ca (HSO3)2
Calcium hydrogen sulphite
