Chlorine gas was passed over a heated substance X. A compound Y is formed which sublime in the tube. Substance Y is soluble in water and on adding sodium hydroxide a white precipitate is formed which is soluble in excess. A solution of Y also gives a white precipitate with ammonium which is soluble in excess. Suggest the nature of substances X and Y and explain the above reactions.
