Chemistry - Salt Analysis Question with Solution | TestHub

A mixture contains red solid (A) and a colourless solid (B) in more than double the amount of (A). This gives violet or lilac colour in the Bunsen flame. The following observations are made with this solid mixture.

i) Solution of the mixture gives black precipitate (C) by passing H₂S in the presence of HCl

ii) (C) is soluble in aquaregia and form black or grey precipitate with SnCl₂

iii) The sodium carbonate extract of Salt with FeCl₃ /CCl₄ gives violet layer

iv) The sodium carbonate extract of salt gives yellow precipitate with AgNO₃ solution, which is insoluble in NH₃ solution.
