Experimental Remarks:
Note:
There are many arithmetical errors in this paper. The compilers have calculated and recalculated all the data in the above Table. The compilers have used only the weights of solutions and weights of SrSO

Method/Apparatus/Procedure:
The isothermal method was used. The thermometer was graduated in tenths of a degree C. The strontium content was determined gravimetrically as SrSO

.
Source and Purity of Materials:
Strontium formate was prepared by the reaction of the carbonate with formic acid.
Estimated Errors:
Temperature: The temperature was controlled to within ±0.02 °C.See note under Experimental Values.
