Calcium nitrate

Water solubility

Link to relevant study record(s)

Reference

Reference 1

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

Justification for type of information:

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:

not specified

Water solubility:

56.7 other: wt%

Temp.:

20 °C

Remarks on result:

other: No data on pH in the handbook

Water solubility:

59 other: wt%

Temp.:

25 °C

Remarks on result:

other: No data on pH in the handbook

Conclusions:

From the CRC Handbook of Chemistry and Physics (80th ed.) it was concluded that calcium nitrate is very soluble in water (> 100 g/L).

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

Justification for type of information:

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:

> 100 g/L

pH:

6

Remarks on result:

other: Temperature not specified

Very soluble in water, heat being evolved. pH of 5% aq soln 6.0.

Conclusions:

According to The Merck Index (12th ed.) calcium nitrate is very soluble in water (> 100 g/L).

Reference 3

Endpoint:

water solubility

Type of information:

other: handbook

Adequacy of study:

weight of evidence

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.

Guideline:

other: not mentioned

Principles of method if other than guideline:

Method followed unknown; data from handbook.

GLP compliance:

not specified

Water solubility:

> 100 g/L

Remarks on result:

other: Temperature and pH not specified

Very soluble in water

Conclusions:

According to Sax's Dangerous Properties of Industrial Materials (9th. ed.) calcium nitrate is very soluble in water (> 100 g/L).

Description of key information

From three handbook results it was concluded that calcium nitrate (anhydrous) is very soluble in water.

Key value for chemical safety assessment

Water solubility:

100 g/L

at the temperature of:

20 °C
