Description and Uses
Mercury(I) fluoride or mercurous fluoride, Hg2F2, consists of small yellow cubic crystals, which turn black when
exposed to light. Mercury(I) fluoride is formed by the reaction of mercury(I) carbonate with hydrofluoric acid.
Hg2CO3 + 2HF→Hg2F2 +CO2 +H2O
Mercury(I) fluoride is used as antiseptic. It is used in the Swarts reaction to convert alkyl halides into alkyl fluorides.
