Dissolve 2.0 g in 50 mL of hydrochloric acid (~70 g/l) TS, and filter. Wash the residue with water and dry to constant mass at 105 °C; the residue weighs not more than 40 mg (2.0%).
Calamine is a basic zinc carbonate suitably coloured with iron(III) oxide. CHARACTERISTICS. An amorphous, impalpable, pink or reddish brown powder, the colour depending on the variety and amount of iron(III) oxide present and the process by which it is incorporated. Practically insoluble in water.
Description An amorphous, pink or reddish brown powder, the colour depending on the variety and amount of iron (III) oxide present and the process by which it is incorporated. Solubility Practically insoluble in water. It dissolves with effervescence in hydrochloric acid. Identification Passes test. Residue on ignition 68 – 74%
Water soluble dyes: Passes test Alcohol soluble dyes: Passes test Loss on ignition: Max 2.0%
Water temperature can have a significant effect on the solubility of compounds. Refer to the chart below to find reference values per gram of common compounds and salts (with chemical formula) at six temperatures of 100 g of water from 0 degrees to 100 degrees Celsius.
The solubility specified here was measured in water. The solubility is influenced by many factors in the application.
