The hydrated compound (CrF.5H2O)SiF0 is stable in dry air or in a vacuum but in contact with moist air it slowly loses silicon tetra-fluoride, and ultimately yields hydrated chromic fluoride, Cr2F5.7ll20. 

HYDRoaEN fluoride rarely occurs free in nature but its presence has been detected in the effluvia from vents in volcanic districts for example, R. V. Matteucci found it in the gaseous products of the fumeroles of Vesuvius. Hydrogen fluoride is formed by the direct union of the elements and by the action of fluorine on water, ammonia, hydrocarbons, and many organic compounds. It is also formed by the action of steam on some of the metal fluorides—-lead fluoride, silver fluoride, etc.—and by the action of some fluorides on water—e.g. iodine pentafluoride. The fluorides and fluosilicates are decomposed by sulphuric acid, with the evolution of hydrogen fluoride—the reaction is incomplete with hydrochloric acid in place of sulphuric acid. G. Gore used chromic fluoride and sulphuric acid R. Luboldt decomposed cryolite with the same acid. 

C. Poulenc i prepared chromium difluoride, or chromous fluoride, CrFg, by the action of hydrogen fluoride on red-hot chromium and by the action of hydrogen fluoride on chromous chloride at ordinary temp. A. Mourlot obtained it by the action of hydrogen fluoride on chromous sulphide. G. Herrmann did not obtain good yields in the electrolytic reduction of chromic fluoride soln. 

Magnanini studied the absorption spectrum and A. Speransky found that the electrical conductivity of aq. soln. shows that only a small proportion of the salt is ionized. The soln. of the violet modification conducts electricity three times better than that of the green. G. Gore electrolyzed a cone. soln. of chromic fluoride acidified with hydrofluoric and hydrochloric acids, and found that the liquid became hot no gas was liberated at the cathode, but chlorine and ozone were liberated at the platinum anode which was not corroded. C. Poulenc showed that the salt is reduced by hydrogen at dull redness. The heat of formation is 230-95 Cals, per mol—vide infra, the dichloride. Steam transforms chromic fluoride into chromic oxide. Chromic fluoride is insoluble in water, and alcohol hydrogen chloride transforms it into chromic chloride hot hydrochloric, sulphuric, and nitric acids attack chromic fluoride only a little hydrogen sulphide converts it into black sulphide and molten alkali nitrate or carbonate converts it into chromate. A. Costachescu prepared complex pyridine salts.
