1. Character: Colorless crystal, hexagonal system. It is hexagonal or amorphous lamellar crystals, odorless.
2. Density (g/mL, 20 C): 2.36.
3. Melting point (unitary C): 350.
4. Refractive index (n20/D): 1.561 or 1.581.
5. Solubility: Soluble in dilute acid and ammonium salt solution, almost insoluble in water and alcohol.
6. Density: 2.36 (20 C).
Introduction:
Magnesium hydroxide is also called caustic magnesite, light burnt magnesia, etc. The suspension of magnesium hydroxide in water is called magnesium hydroxide emulsion, short for magnesium emulsion, English name is Magnesium hydroxide. Magnesium hydroxide is a colorless hexagonal crystal or white powder, insoluble in water and alcohol, soluble in dilute acid and ammonium salt solution, aqueous solution is alkaline. The solubility in water is very small, high school students think it is weak electrolyte. Magnesium hydroxide natural mineral brucite. It can be used to make sugar and magnesium oxide.
Storage method:
保持贮藏器密封、储存在阴凉、干燥的地方,确保工作间有良好的通风或排气装置。 Store in a dry warehouse. Packaging should be completely sealed to prevent dampness. It should not be stored and mixed with acid substances.
