A white crystalline solid (A) on boiling...

A white crystalline solid (A) on boiling with caustic soda solution gave a gas (B), which when passed through an alkaline solution of potassium mercuric iodide gave brown precipitate. The substance (A) on heating gave a gas (X), which rekindled a glowing splinter but did not give brown fumes with nitric oxide. the gas (B) is:

A

`H_(2)S`

B

`NH_(3)`

C

`HCI`

D

`CO_(2)`

Text Solution

Verified by Experts

The correct Answer is:
B

`underset((A))(NH_(4)^(+)) overset(NaOH)rarr underset((B))(NH_(3)) overset(K_(2)HgI_(4))underset(OH^(-))rarr underset(("Brown ppt"))(Hg(NH_(2))I darr)`

A white crystalline solid (A) on boiling with caustic soda solution gave a gas (B) which when passed through an alkaline solution of K_(2) [HgI_(4)] gave a brown precipitate. The substance (A) on heating gave a gas (X) which rekindled a glowing splinter but does not give brown fumes with nitric oxide. The gas (X) is:

Explain why a green solution of potassium manganate turns purple and a brown solid is precipitated when CO_(2) gas is bubbled into the solution.
