Methodology:
The only information given is that the solubility values were determined by the freezing point method.
Sample Information:
- The lithium salt was prepared by dissolving the carbonate in 90% formic acid. The salt was dried at 373 K and purified by recrystallizing from alcohol and drying over sulfuric acid in a vacuum. Formic acid was prepared by treating a c.p. product with $\ce{B2O3}$. It was then distilled in vacuo until a product melting above 281.6 K was obtained.
Measurement Errors:
Ambient temperature: Nothing is specified.
Mass concentration (m/v) (1): Nothing is specified.
System Components:
- Lithium formate, $\ce{ LiCHO2 }$; [556-63-8] NIST WebBook
- Formic acid, $\ce{ CH2O2 }$; [64-18-6] NIST WebBook
