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.

Water solubility of dihydrate and hexahydrate: soluble and very soluble, resp.

Conclusions:
From the CRC Handbook of Chemistry and Physics (80th ed.) it was concluded that magnesium nitrate in its anhydrous or dihydrated form is soluble (1000-10000 mg/L) in water and very soluble in water in its hexahydrated form.
Endpoint:
water solubility
Type of information:
other: Safety Card
Adequacy of study:
weight of evidence
Reliability:
4 (not assignable)
Rationale for reliability incl. deficiencies:
documentation insufficient for assessment
Remarks:
From International Chemical Safety Cards. There is 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.
Qualifier:
no guideline followed
Principles of method if other than guideline:
Method followed unknown; data from safety card.
GLP compliance:

Remarks on result:
other: no methodological details were provided (handbook data)

Solubility in water: very good

Conclusions:
From ICSC nr: 1041 (Magnesium nitrate) it was concluded that magnesium nitrate (anhydrous) is very soluble (> 10000 mg/L) in water.
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:
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.

The hexahydrate is soluble in 0.8 part water.

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

Description of key information

From two handbooks and ICSC 1041, it was concluded that magnesium nitrate (anhydrous and hydrated) is soluble (1-10 g/L) to very soluble (> 10 g/L) in water.

Key value for chemical safety assessment

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