Text Solution

Verified by Experts

`Ca(OH)_(2) rarr underset(("X"))(CaO + H_(2)O)`
`Ca(OH)_(2) + HC1 rarr underset(("Y"))(CaC1_(2)) + H_(2)O`
CaO is hygroscopic in nature absorbs moisture and remains in solid state.
`CaC1_(2)` is deliquescent in nature, absorbs moisture and is converted into solution state.
