Ruthenium Sulphate, Ru(SO4)2

Ruthenium Sulphate, Ru(SO4)2, results when the precipitated sulphide is oxidised by solution in nitric acid, and by dissolving barium ruthenate in fuming hydrochloric acid, evaporating to dryness, extracting with water and adding excess of dilute sulphuric acid. The barium is precipitated and the filtrate is concentrated, yielding a red liquid, from which, however, Antony could not obtain the crystalline salt. It is also produced by dissolving the tetroxide in sulphuric acid. On evaporation the orange solution yields a yellowish brown, amorphous residue, which is very deliquescent and easily soluble in water. On warming with alkalies, ruthenium hydroxide is precipitated from solution.
