A Solid product having of having a formula selected from Ce(CH.sub.3 SO.sub.3).sub.2.OxH.sub.2 O and Ce(CH.sub.3 SO.sub.3).sub.2 (OH).sub.2 O.xH.sub.2 O wherein x is an integer equal to or greater than 1.
A product comprising ceric methanesulfonate hydroxide hydrate formed by contacting, in an aqueous medium, a cerous salt selected from cerous oxide, cerous carbonate, cerous hydroxide or mixtures thereof with from 0.1 to 1.3 molar excess of methanesulfonic acid sufficient to form cerous methanesulfonate and said cerous cations are present in at least 0.2 molar concentration;
- electralytically oxidizing the cerous ions to ceric ions;
- and separating the solid ceric methanesulfonate hydroxide hydrate from the aqueous medium.
