An inorganic compound (X) gives a brick ...

An inorganic compound `(X)` gives a brick red flame on performing flame test. This compound gives the following tests also.
(a) Smells of chlorine when placed in moist air.
(b) If `KI` and `CH_(3)COOH` are added to the suspension in water, a brown colour is obtained.
Identify `(X)` and down equations for reactions at steps (a) and (b) .

Text Solution

Verified by Experts

Compound `(X)` gives a brick red flame in flame test. Thus, it is a calcium compound. The smell of chlorine on exposure suggests that it is a bleaching powder. It is confirmed by reaction (b).
(a) `6CaOCl_(2) rarr 5CaCl_(2)+Ca(CIO_3)_(2)`
`CaOCl_(2)+CO_(2) rarr CaCO_(3)+Cl_(2) uarr`
(b) `CaOCl_(2) + 2CH_(3)COOH rarr (CH_(3)COO)_(2)Ca+H_(2)O+Cl_(2)`
`2KI+Cl_(2) rarr 2KCl+I_(2)`.
