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 , it gave deep red colour which disappeared on boiling and a brown red ppt was formed. The mixture contains (1) \ce{SO3^2- & CH3 COO^-} (2) \ce{CH3 COO^- & NO3^-} (3) \ce{SO3^2- & C2O4^2-} (4) \ce{C2O4^2- & NO3^-}
- a
\ce{SO3^2- & CH3 COO^-}
- b✓
\ce{CH3 COO^- & NO3^-}
- c
\ce{SO3^2- & C2O4^2-}
- d
\ce{C2O4^2- & NO3^-}
\ce{CH3 COO^- & NO3^-}
