- Endpoint:
- melting point/freezing point
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- test procedure in accordance with generally accepted scientific standards and described in sufficient detail
- Justification for type of information:
- Experimental test result performed using standard test guidelines
- Qualifier:
- according to guideline
- Guideline:
- other: as mentioned below
- Principles of method if other than guideline:
- A solution freezes at a lower temperature than does the pure solvent. This phenomenon is called freezing point depression. The freezing point depression of a solution is a colligative property of the solution which is dependent upon the number of dissolved particles in the solution. The higher the solute concentration, the greater the freezing point depression of the solution. The freezing point of the pure solvent is at constant temperature but the freezing point of the solution slowly decreases.
- GLP compliance:
- no
- Type of method:
- method to determine freezing temperature
- Remarks:
- Freezing point depression of Pure solvent
- Key result
- Melting / freezing pt.:

- Conclusions:
- The freezing point was determined to be -18°C at 96990 Pa.
- Executive summary:
The freezing point of test chemical was determined. The method followed was referred to as freezing point depression. The freezing point was determined to be -18°C at 96990 Pa.
