Endpoint:
water solubility
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:
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.
Guideline:
other: not mentioned
Principles of method if other than guideline:
Method followed unknown; data from handbook.
GLP compliance:

Conclusions:
According to the CRC Handbook of Chemistry and Physics (80th ed.) sodium nitrate is very soluble in water (> 10000 mg/L).
Endpoint:

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.

Water solubility:
> 10 000 mg/L
Remarks on result:
other: temperature and pH were not specified

One gram dissolves in 1.1 mL water. When dissolved in water, the temp of the soln is lowered. The aq soln is neutral.

Conclusions:
According to the Merck Index (12th ed.) sodium nitrate is very soluble in water (> 10000 mg/L).
Endpoint:

Reliability:
4 (not assignable)
Rationale for reliability incl. deficiencies:
documentation insufficient for assessment
Remarks:
The preface and introduction to this book (9th Edition) provide no indication that the physico-chemical data has been ‘peer reviewed’. The reference source is not indicated leading to insufficient information on the material & method used.

Very soluble in water

Conclusions:
Sax's Dangerous Properties of Industrial Materials (9th. ed.) mentions that sodium nitrate is very soluble in water (> 10000 mg/L).

Description of key information

From three handbooks it was concluded that sodium nitrate is very soluble in water.

Key value for chemical safety assessment

Water solubility:
100 g/L
at the temperature of:
20 °C
