Identification method of magnesium sulfate monohydrate


The function of magnesium sulfate monohydrate has been continuously tapped, so the demand in the chemical industry will continue to increase. But for the user who just tried to use it, it can't be correctly and professionally identified. Here we provide you with the main identification methods, let's take a look:

1. According to its appearance and properties: magnesium sulfate monohydrate is a white powder, easily soluble in water, slightly soluble in ethanol and glycerin, ether, and insoluble in acetone.

2. Take 1 g of sample, dissolve in 10 ml of water, add ammonia water to precipitate white, and add appropriate amount of ammonium chloride to dissolve. Adding a 5% disodium hydrogen phosphate solution, a white precipitate is formed, and it does not dissolve after adding ammonia water, which proves that it is genuine.


  Magnesium sulfate monohydrate is often used in tanning, explosives, papermaking, porcelain, fertilizers, and oral laxatives in medicine. It has a higher solubility than other fertilizers and is also used as a bath salt based on this characteristic.
