Highly toxic by ingestion, inhalation, and
skin absorption; strong irritant. | [Chemical Properties]
yellow to pink powder | [Preparation]
Mercury(II) fluoride, HgF2, is most commonly prepared through the reaction of mercury(II) oxide with hydrogen
fluoride.
HgO + 2HF→HgF2 + H2O
It can also be produced through the fluorination of mercury(II) chloride.
HgCl2 + F2→HgF2 + Cl2 | [reaction suitability]
reagent type: catalyst
core: mercury |
