The word "sulphate" is used when referring to a chemical molecule that consists of oxygen and sulfur atoms. It is used to describe a molecule that creates salt when combined with other elements, such as potassium, magnesium, sodium, barium, and calcium. In chemistry, a sulphate is a group of atoms, anions, or inorganic ions.
