A certain compound `(X)` shows the following reactions.
(a) when `Ki` is added to an aqueous suspention of `(X)` containing acetic acid, iodine is liberated.
(b) when `CO_(2)` is passed through an aqueous suspension of `(X)` the turbidity transforms to a precipitate.
(c ) When the past of `(X)` in water is heated with ethyl alcohol, a product of anaesthetic use is obtained. Identify `(X)` and write down chemical equations for reactions at steps (a), and (c ).

Text Solution

Verified by Experts

Compound `(X)` is bleaching powder, `CaOCl_(2)`.
(a) `CaOCl_(2)+KI+2CH_(3)COOH rarr Ca(CH_(3)COO)_(2)+2KCl+H_(2)O+I_(2)`
(b) `CaOCl_(2(aq))+CO_(2(g)) rarr underset("White ppt.")(CaCO_(3(s)) + Cl_(2(g))`
(c ) `Ca(OCl)CI+H_(2)O rarr Ca(OH)_(2)+Cl_(2)`
`C_(2)H_(5)OH+CI_(2) rarr CH_(3)CHO+HCl`
`CH_(3)CHO+3Cl_(2) rarr CH_(3)CHO+HCl`
`CH_(3)CHO+3Cl_(2) rarr C CI_(3)CHO+3HCl`
`2C CI_(3)CHO+Ca(OH)_(2) rarr 2CH_(3)+(HCOO)_(2)Ca`
