Observation table:

Method Details		Observations	Remarks if, any
Method	Method according to Cooling Curve
Principle of Freezing point test	The freezing point of a pure sample is determined by making measurements of the temperature as a function of time while the sample is submerged in a constant temperature bath at a temperature below that of the expected freezing point of the sample. The data (Temperaturevs.time) is plotted; this plot is known as acooling curve. The freezing point is the value of temperature in the flat portion of the curve.

Conclusions:

The Freezing point determination of test chemical was done using crushed ice and salt bath. The determination was done on the basis of cooling curve (time vs temperature) obtained when the test chemical was placed in the cooling bath. No crystallization was observed up to -14.3°C. Hence, the freezing point was concluded to be less than -14.3 °C at 977.1 hPa.

Executive summary:

The Freezing point determination of test chemical was done using crushed ice and salt bath. The determination was done on the basis of cooling curve (time vs temperature) obtained when the test chemical was placed in the cooling bath. No crystallization was observed up to -14.3°C. Hence, the freezing point was concluded to be less than -14.3 °C at 977.1 hPa.
