Conditions:
Compiler:
Methodology:
A visual polythermal method was used. The temperatures were measured with a Nichrome-Constantan thermocouple.
Sample Information:
- Analytical grade materials were recrystallized twice. The extrapolated fusion temperature of the lithium formate was 273°C.
Measurement Errors:
Ambient temperature: The compiler estimates the accuracy of the temperature measurement to be probably ±0.2 K.
Mass concentration (m/v) (1): No information is given.
