Calcium - Wikipedia

Calcium is a chemical element with the syol Ca and atomic nuer 20. As an alkaline earth metal, calcium is a reactive metal that forms a dark oxide-nitride layer when exposed to air. Its physical and chemical properties are most similar to its heavier homologues strontium and barium. It is the fifth most abundant element in Earth''s crust

METHOD 7000B FLAME ATOMIC ABSORPTION SPECTROPHOTOMETRY

magnesium, calcium, and barium determinations. Similarly, silica interference in the determination of manganese can be eliminated by the addition of calcium. A nitrous oxide/acetylene gas mixture may be used to help prevent interferences from refractory 4.3

Determination of Total Calcium and Magnesium Ion Concentration

The dye–metal ion complex is less stable than the EDTA–metal ion complex. For the titration, the sample solution containing the calcium and magnesium ions is reacted with an excess of EDTA. The indior is added and remains blue as all the Ca2+ and Mg2+

Magnesium: appliions and uses-Metalpedia

Magnesium is the lightest of all light metal alloys and therefore is an excellent choice for engineering appliions when weight is a critical design element. It is strong, has good heat dissipation, good damping and is readily available. Its properties make it easy to weld, forge, cast or machine. It can be alloyed with other metals, making
