An inorganic compound [A] yellowish green in colour loses its water of crystallisation upon heating . When heated furthr, it changes to blackish brown powder [B] and also gives two oxides of sulphure. The power [B] on boiling with hydrochloric acid given a yellowish solution which gives a bloodred colouration on reacting with potassium thiocyanate.
The yellow solution is of

A

ferrous chloride

B

manganese sulphate

C

ferric chloride

D

aluminium sulphate.

Text Solution

Verified by Experts

The correct Answer is:
C
(c) Since the yellowish solution formed in the reaction gives blood red colour with KCNS, it is of ferric chloride `(FeCl_(3))`.
