Re: MnCl2 won't dissolve?
The change in color of the light pink MnCl2 solution to light brown and the appearance of a very fine light brown precipitate when left for several hours may suggest oxidation of Mn²⁺ to MnO(OH). This can occur in demineralized water environments, slope especially when air is present.
