Manganese(II) sulfate (MnSO4) is colorless because it is a salt formed from manganese in the +2 oxidation state, which does not have unpaired d-electrons that would allow for d-d electronic transitions. In its hydrated form, MnSO4 typically appears as a pale pink solid, but when dissolved in water, it becomes colorless due to the lack of chromophores that absorb visible light. The sulfate ion (SO4^2-) is also colorless, contributing to the overall colorless appearance of the solution.
