Magnesium Silicate PR (MagSil PR), also known as Magnesium Silicate Hydrate, Soapstone, and Talcum, is often available as hydrate having the chemical formula MgO:XSiO2-H2O, where X denotes the average mole ratio of SiO2 to MgO. It appears as an off-white odorless solid and is insoluble in Water. It is often produced by the precipitation reaction of water-soluble Sodium Silicate and a water-soluble Magnesium salt (like Magnesium Chloride or Nitrate). 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. Due to its high purity, this Lab Alley product is highly recommended for labs and commercial applications.
