Question

A solution of white solid (A) gave white precipitate (B) with water. On treatment with HCl, the ppt B produced A. The solution of A gives black precipitate (C) on reacting with sodium stanite and NaOH The compound A gives a colourless gas (D) with concentrated H, SO4. The gas is soluble in water and its aqueous solution produce with it precipitate with Hy, (NO3), but no precipitate with Hg(NO3)2. Identify (A) to (D) and write the chemical reactions involved​

Answer 1

Answer:

Here's your answer.

A = BiCl3

B = BiOCl
