White colourless crystal | [General Description]
Magnesium nitrate hexahydrate is a hydrated magnesium salt. A mixture of magnesium nitrate hexahydrate and magnesium chloride hexahydrate has been reported as a potential phase change material (PCM) for the storage of latent thermal energy. It has been employed as a base material in this mixture to evaluate the storage and effective utilization of urban waste heat from emerged co-generation systems. Its crystals belong to the monoclinic crystal system. | [Purification Methods]
Crystallise the nitrate from water (2.5mL/g) by partial evaporation in a desiccator. It is deliquescent and is soluble in EtOH. After two recrystallisations, ACS grade salt has: metal (ppm) Ca (6.2), Fe (8.4), K (2), Mo (0.6), Na (0.8), Se (0.02). |
| Questions And Answer | Back Directory | [Uses]
Sodium bisulfate is used for pickling metals; bleaching leather; carbonizing
wool; in carbonic acid baths, and manufacturing magnesia cements. | [Production Methods]
Sodium bisulfate is a by-product of sodium sulfate manufacture. One process involves reacting sulfuric acid with sodium nitrate at high temperature to form nitric acid and sodium bisulfate:
NaNO3 + H2SO4 → NaHSO4 + HNO3 (g)
In the above reaction, nitric acid is obtained as vapor. It is purged from the system and collected in water to obtain nitric acid solution of desired concentration. Sodium bisulfate is separated by fractional crystallization.
