Technical Specification
| Appearance: (USP) | Pale bluish-green crystals or granules. Oxidizes readily in moist air to form brownish yellow basic ferric sulfate |
|---|---|
| Appearance: (EP, BP) | Light green, crystalline powder or bluish-green crystals, efflorescent in air. Ferrous sulfate heptahydrate is oxidised in moist air, becoming brown. |
| Appearance: (JP) | Pale green crystals or crystalline powder. It is efflorescent in dry air, and its surface becomes yellowish brown in moist air. |
| Appearance: (IP) | Bluish green crystals or a light green, crystalline powder. Efflorescent in air. On exposure to moist air, the crystals rapidly oxidise and become brown. |
| Solubility: (USP) | Very soluble in boiling water, freely soluble in water, insoluble in alcohol |
| Solubility: (EP, BP) | Freely soluble in water, very soluble in boiling water, practically insoluble in ethanol (96%) |
| Solubility: (JP) | Freely soluble in water, and practically insoluble in ethanol (95%), and in diethyl ether |
| Solubility: (IP) | Very soluble in boiling water, freely soluble in water, practically insoluble in ethanol (95%) |
| Identification : (JP) | Gives the reaction for ferrous salt and for sulphate |
| Identification : (IP) | Gives reaction (A) of ferrous salts and the reactions of sulphates |
| Identification A Iron, ferrous salts and sulfate : (USP) | Meets the requirements |
| Identification A, Sulfates : (EP, BP) | Gives the reactions of sulphates |
| Identification B, Iron : (EP, BP) | Gives the reaction (a) of iron |
| Identification C: (EP, BP) | Complies with the limit of the assay |
| pH (5% in water) : (EP, BP, IP) | 3.00-4.00 |
| Clarity of solution : (JP) | The solution is clear |
| Appearance of solution : (IP) | The solution is not more opalescent than opalescence standard OS2 |
