CO AS चेतो also added before adding the thioacetamide? (HC) 4. A solution was known to contain only Group II cations. When the solution was made acidic, treated with thioạcetamide and heated, it yielded a dark precipitate (A) and an olive-colored decantate (X). When precipitate (A) was treated with HNO, it completely dissolved to form colorless solution (B). Addition of NH,(aq) produced a white gelatinous precipitate in a colorless solution. Decantate (X) was treated with NH,Cl, NH,(aq), thioacetamide and heated to produce a dark precipitate (Y). The dark precipitate (Y) dissolved completely in a mixture of concentrated nitric and hydrochloric acids. Indicate for each ion in Group II whether it was definitely present, definitely absent, or that you cannot deciue from the information given. RIcopo Sac
