Salts A,B,C,D and E undergo reactions (a) to (e) respectively. Identify the anions present in these salts on the basis of these reactions (also write the equations for them assuming each to be Sodium salts) (a) When silver nitrate solution is added to a solution of A, a white precipitate, insoluble in dilute nitric acid, is formed. (b) Addition of dilute hydrochloric acid to B produces a gas which turns lead acetate paper black. (c) When a freshly prepared solution of ferrous sulphate is added to a solution of C and concentrated sulphuric acid is gently poured from the side of the test-tube, a brown ring is formed. (d) When dilute sulphuric acid is added to D, a gas is produced which turns acidified potassium dichromate solution from orange to green. (e) Addition of dilute hydrochloric acid to E produces an effervescence. The gas produced turns limewater milky but does not affect acidified potassium dichromate solution.
