Notes:
   a  The T/K values were calculated the compiler.
   b  This is the eutectic.

Method/Apparatus/Procedure:
   A visual polythermal method was used. The salts were melted in a test tube. The temperatures were measured with a Nichrome-Constantan thermouple and a 17mV full scale millivoltmeter.

Source and Purity of Materials:
   Component (1) was synthesized from formic acid and NaHCO3. Component (2) was a commercially available product and was further purified by the author according to Laiti.

Estimated Errors:
   Solubility: No information is given.
   Temperature: The compiler estimates the accuracy of the temperature measurements to be probably ± 2 K.
