Identification of Ions

When a solution of mixture having two inorganic salts was treated with freshly prepared ferrous sulphate in acidic medium, a dark brown ring was formed whereas on treatment with neutral ${\mathrm{FeCl}}_3$, it gave deep red colour which disappeared on boiling and a brown red ppt was formed. The mixture contains
