Overview
About Mercuric Oxide Yellow
Mercuric Oxide Yellow is precipitated mercury(II) oxide. Its finer particles make it more reactive than the red form, which suits reagent and synthesis work.
Every batch is tested for insoluble matter, residue on reduction, chloride, iron, nitrogen compounds and sulphate.
