FAQs on Magnesium Phosphate

Q: What are the primary sources of magnesium phosphate?

A: Legumes, avocado, nuts, pumpkin, and multiple fatty fishes such as salmon, mackerel, etc., have high amounts of magnesium. Simultaneously, one can derive phosphorus from chicken, pork, pumpkin, dairy products, cuttlefish, crab, etc.

Q: What is Calcium Magnesium Phosphate?

A: When calcium ion is included in magnesium phosphate, it becomes calcium magnesium phosphate. The chemical formula is CaMgO4P.

Q: Is magnesium phosphate a naturally occurring substance?

A: Magnesium and Phosphorus are abundant in nature. However, it is the heat treatment of both the minerals that form magnesium phosphate.

Q: Differentiate between phosphate, phosphorous, and phosphoric acid.

A: Phosphorus is an essential mineral for animal and plant life. Phosphate is a naturally occurring compound that contains phosphorus and other minerals. In comparison, phosphoric acid is an inorganic acid that is essentially used for derivations of phosphates.

Q: What percentage of magnesium phosphate is phosphorus?

A: Phosphorus is 23.56% in magnesium phosphate.
