Conclusions:
The freezing point of test chemical was determined. The method was used crushed ice and salt at respective atmospheric pressure using Micro LAB Interface FS–524 data generation system and thermistor as temperature detection system. The test was conducted in replicates and mean freezing point was determined to be -5.37°C at 97830 Pa.
Executive summary:

The freezing point of test chemical was determined. The method used was crushed ice and salt at respective atmospheric pressure using Micro LAB Interface FS–524 data generation system and thermistor as temperature detection system. The test was conducted in replicates and mean freezing point was determined to be -5.37°C at 97830 Pa.
