Barium Sulfate, Formula, Chemical Properties, Preparation, Uses

Barium Sulfate

Barium sulfate is an inorganic compound that has consists of barium and sulfate. The barium has positively charged and sulfate has negatively charged and acts as the cations and anions respectively. It requires to obtain the coke and then seggrated from the impurities. It occurs naturally in the mineral barite. After the process of mining it has been obtained from the barite. The systematic IUPAC name is known as barium sulfate. The chemical or molecular name of barium sulfate is BaSO4.

Structural Formula

This is the structural formula of the barium sulfate:
