Except where noted otherwise, data are given for materials in their standard state (at 25 °C, 100 kPa)Infobox references 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]:
- Hg2(NO3)2 + SO42- → Hg2SO4 + 2 NO3-
It can also be prepared by reacting an excess of mercury with concentrated sulfuric acid[4]:
- 2 Hg + 2 H2SO4 → Hg2SO4 + 2 H2O + SO2
