In the EDTA titration for CaO in limestone, the pH of the sample is made sufficiently basic so any magnesium thatis present will precipitate as Mg(OH)2. The adjustment of pH is fairly […]
Once upon a time, a common method for determining phosphorous was to convert it to phosphate, precipitate it as magnesium ammonium phosphate, MgNH4PO4, and ignite it to form magnesium pyrophosphate, Mg2P2O7. The […]
You may know that there is a growing interest in the ginkgo tree because herbal supplements using extracts of ginkgo are believed to aid in fighting memory loss. A recent paper [Lang, […]
Milk of Magnesia, or MOM, is a suspension of Mg(OH)2. One method for determining the amount of Mg(OH)2 in MOM is to precipitate the Mg2+ as MgNH4PO4. Because this precipitate includes a […]
