The Magnesium hydroxide is insoluble

Magnesium hydroxide is a common hydroxide, so is Magnesium hydroxide precipitation? Is Magnesium hydroxide a deposit? Magnesium hydroxide is insoluble in water. It is a deposit. The Magnesium hydroxide is a colorless hexagonal column crystal or white powder. It is soluble in dilute acid and ammonium salt solutions, and the aqueous solution is weakly alkaline. The solubility in water is very small, but the water-soluble part is completely ionized. In general, all hydroxide except sodium hydroxide, potassium hydroxide, barium dihydroxide, ammonia are soluble in water, and calcium dihydroxide are slightly soluble in water. All other hydroxide are difficult to dissolve in water. The Magnesium hydroxide suspension in the water is called an emulsion of magnesium hydroxide, or simply milk of magnesium, used to neutralize excess stomach acid and treat constipation. Magnesium hydroxide is an excellent flame retardant for plastics and rubber products. As a flue gas desulfurization agent, it can replace caustic soda and lime as neutralizer of acid-containing wastewater. It is also used as oil additive to prevent corrosion and desulphurization. In addition, it can also be used in electronics industry, medicine, sugar refining, as insulation materials and manufacturing other magnesium salt products. The Magnesium hydroxide can be used as chemical materials and intermediates because of its excellent cushioning, reactivity, adsorption and thermal decomposition properties, it is also a green environmental flame retardant and additives used in rubber, plastic, fiber and resin and other polymer materials industry.
