WebNo doubt, Co(NO3)2 can react with conc. HCl to give CoCl2 but there is always a possibility of formation complex[ CoCl4]^2- . So it is indirectly prepared as: Heat strongly to form CoO: WebAfter conc HCl was added, the color was purple. The solution produced this color because the ligands Cl- and H2O bonded to the cobalt (II) ion have the equilibrium shifted right. The equilibrium goes right because the formation of [CoCl2]2- increases the chloride ion concentration and water. Thus the addition of HCl moves the equilibrium right ...
