Brown ring is formed by adding ferrous sulphate solution to the salt. This confirms the presence of which anion?
Identify the anion present in the salt on the basis of the reaction given below
When a freshly prepared solution of ferrous sulphate is added to a salt solution and concentrated sulphuric acid is gently poured from the side of the test tube, a brown ring is formed.
In brown ring test, a freshly prepared ferrous sulphate solution is used because:
