Question
Moreover, the salt 'A' on heating with solid K2Cr2O7 and concentrated H2SO4 produces deep red vapours which dissolve in sodium hydroxide solution forming a yellow solution. This yellow solution gives yellow precipitate with Ba(NO3 ) 2 solution. On the basis of the aforesaid characteristic informations answer the following questions :
Select the correct statement.
- Aqueous solution of 'A' reacts with AgNO3 solution to give white precipitate which turns yellow on treatment with sodium arsenite.
- Aqueous solution of 'A' produces white precipitate with sodium hydroxide which turns yellowish-white on boiling.
- White turbidity 'E' is soluble in dilute mineral acids.
- All of these
The correct answer is: All of these
