Mercury(I) sulfate, commonly called mercurous sulfate (US) or mercurous sulphate (UK) is the chemical compound Hg2SO4.[3] It can be produced by a reaction of mercury(I) nitrate with a source of sulfate ions[4]:
It can also be prepared by reacting an excess of mercury with concentrated sulfuric acid[4]:
