Strontium Formate, Sr(HCO2)2, is formed in solution by neutralising formic acid with strontium oxide or carbonate. From this solution a dihydrate of density 2.667 crystallises out below about 83° C., and above that temperature the anhydrous salt of density 2.250.
The dihydrate exists in two different rhombic crystalline forms. The freezing-point lowering of water produced by strontium formate has been determined. The molecular refractivity is 49.01.
A double strontium copper formate, 2Sr(HCO2)2.Cu(HCO2)2.2H2O, of density 2.133, has been prepared. |
