Strontium Oxalate, SrC2O4
Strontium Oxalate, SrC2O4, may be obtained as the monohydrate by precipitation from a concentrated solution of strontium chloride by ammonium oxalate. At low temperatures it crystallises with 2½ molecules of water. The solubility of strontium oxalate at 18° C., as calculated from electrical conductivity determinations, is 0.26 millimole, or 46.1 mgm. of anhydrous salt per litre. A small quantity of acetic acid increases the solubility of strontium oxalate, which reaches a maximum in approximately 4N acid. By higher concentrations the solubility is again diminished.
