Barium Phosphate, Formula, Chemical Properties, Preparation, Uses

Barium Phosphate

Barium phosphate is an inorganic salt compound that has consists of barium and phosphate. Generally it has a colourless solid which is similar to the acetic acid. The barium phosphate is considered as the 3 cations and 2 anions. It has been linked to the sharing oxygen atom with the structural formula. The systematic IUPAC name is known as barium phosphate. The chemical or molecular name of barium phosphate is Ba3(PO4)2. It is also known as tribarium diphosphate.

Structural Formula

This is the structural formula of the barium phosphate:

Barium Phosphate

Chemical Formula

The chemical formula of the barium phosphate in Ba3(PO4)2. It has cosists of three barium and diphosphate and oxygen ions.

How it is Prepared

When the barium carbonate is reacted with the metaphosphoric acid it gives the product of barium phosphate and carbon dioxide, water is the byproduct. It can be precipitated and slowly removed from the cations. It could be commonly involved in the aqueous solution and that has been in the anhydrous form. The chemical reaction is given as follows.
