$\left[\mathrm{C}\mathrm{r}\right(\mathrm{N}{\mathrm{H}}_3{)}_5\mathrm{C}\mathrm{l}]\mathrm{S}{\mathrm{O}}_4$ionise as$\left[\mathrm{C}\mathrm{r}\right(\mathrm{N}{\mathrm{H}}_3{)}_5\mathrm{C}\mathrm{l}{]}^{2+}$and$\mathrm{S}{\mathrm{O}}_4^{2-}$and its aqueous solution will give test for$\mathrm{S}{\mathrm{O}}_4^{2-}$ions.
$\mathrm{B}\mathrm{a}\mathrm{C}{\mathrm{l}}_2\left(\mathrm{a}\mathrm{q}\right)+\mathrm{S}{\mathrm{O}}_4^{2-}\to \mathrm{B}\mathrm{a}\mathrm{S}{\mathrm{O}}_4+2\mathrm{C}{\mathrm{l}}^{-}$
