Details

About Magnesium Hydroxide Lab Grade

Magnesium Hydroxide, also known as Milk of Magnesia and Magnesium Dihydroxide, is an inorganic compound that occurs as a white, odorless, and tasteless powder. It is slightly soluble in water, and is soluble in dilute acids and ammonium salt solutions. It can be precipitated from a Magnesium salt solution by adding Sodium Hydroxide or can be produced by treating purified seawater with Lime.

Chemically pure or Laboratory reagents are the two terms often used to describe Lab Grade chemicals. Lab Grade chemicals do not meet any accepted quality or purity requirements such as the ACS Grade, the USP Grade, and the FCC Grade, despite their acceptable purity.
