Melting point / freezing point
Administrative data
Link to relevant study record(s)
- Endpoint:
- melting point/freezing point
- Type of information:
- other: handbook
- Adequacy of study:
- weight of evidence
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- data from handbook or collection of data
- Remarks:
- Handbook data are considered from a trusted source. Data have been taken from many sources, including both compilations and the primary literature - where conflicts were found, the value deemed most reliable was chosen. The reference was peer-reviewed. In addition, the reference sources are indicated although not leading to sufficient information on the material & method used.
- Qualifier:
- no guideline followed
- Principles of method if other than guideline:
- Method followed unknown; data from handbook.
- GLP compliance:
- not specified
- Key result
- Melting / freezing pt.:
- ca. 100 °C
- Decomposition:
- yes
- Decomp. temp.:
- ca. 100 °C
- Remarks on result:
- other: dihydrate
- Key result
- Melting / freezing pt.:
- ca. 95 °C
- Decomposition:
- yes
- Decomp. temp.:
- ca. 95 °C
- Remarks on result:
- other: hexahydrate
- Conclusions:
- The CRC Handbook of Chemistry and Physics (80th ed.) mentions a melting/decomposition temperature of ca 95ºC and of ca 100ºC for magnesium nitrate hexahydrate and magnesium nitrate dihydrate, resp.
