Storage condition
1. It should be stored in a ventilated and dry warehouse. Do not stack in the open air, pay attention to moisture.

2. Not to be stored and transported with toxic and harmful substances. Be protected from rain and sun during transportation.

3. Handle gently during loading and unloading to prevent breakage of the package and moisture. Fire can be put out with water, sand and various fire extinguishers.

stability
1. Pure products are not deliquescent. It has a bitter, salty taste. It is hygroscopic. The solubility in water increases rapidly with the increase of temperature.

2. Sublimation at about 1500℃. The chlorides of sodium and magnesium reduce their solubility in water. The relative density of saturated aqueous solution at 15℃ is 1.172, and the pH is about 7. It's stimulating.

3. Stable in air. The solubility in 100g water is 34.7g (20℃), 56.0g (100℃). Insoluble in ethanol.
