During the formation of ppt by$\mathrm{M}\mathrm{g}\mathrm{C}{\mathrm{l}}_2$with$\mathrm{C}{{\mathrm{O}}_3}^{2-}$, it will be produced$\mathrm{H}\mathrm{C}{{\mathrm{O}}_3}^{-}$ion in the solution. Hence, we can’t be used to detect the presence of both$\mathrm{C}{{\mathrm{O}}_3}^{2-}$and$\mathrm{H}\mathrm{C}{{\mathrm{O}}_3}^{-}$in a mixture
