Is magnesium hydroxide soluble in water

Insoluble in water.






Magnesium hydroxide is insoluble in water and alcohol, but can be dissolved in acid and ammonium salt solution. The refractive index of magnesium hydroxide is 1.580. Magnesium hydroxide can decompose into magnesium oxide and water. The reaction endothermic capacity is 10.7 kcal / mol, and it begins to decompose at 340 ℃. The speed is the fastest when it reaches 430 ℃, and the decomposition ends when it reaches 490 ℃.


matters needing attention:






Environment is the most basic. It is necessary to keep the storage environment dry and ventilated. It is necessary to lay a layer of plastic film between the product and the ground to isolate water vapor.






The packaging needs to be well sealed. Open the used ones and seal them in time.






Placing lime blocks after stacking to prevent moisture is another way to avoid moisture absorption of magnesium hydroxide and reduce activity.






Because calcium oxide has stronger moisture absorption, calcium oxide is placed in the warehouse as a moisture reducing agent to reduce the humidity of the warehouse, and the effect is remarkable.
