Manganese is a transition metal that can display a range of oxidation states: Mn²+, Mn³+, Mn¹+, Mn6+
and Mn7+ are all known. Here, manganese is in a hydrated compound with the element X. Element X
will precipitate out of the solution as part of an ionic compound if a suitable cation is added.
Conduct an investigation to identify the element X, given the formula MnX.4H₂O (note that the
quantity of X is not specified in the formula).
