Question
Which of the following complexes will give a white precipitate on treatment with a solution of barium nitrate?
- [Cr(NH3)4SO4] Cl
- [Co(NH3)4Cl2] NO2
- [Cr(NH3)4Cl2]SO4
- [CrCl2(H2O)4]Cl
Solution
(c) [Cr(NH3)4Cl2]SO4
[Cr(NH3)4Cl2]SO4 complex will give a white precipitate on treatment with a solution of barium nitrate. The white precipitate is of barium sulphate (BaSO4).
