The sulphate [[ion]] is a group of [[atom]]s with the formula SO<sub>4</sub> and two negative charges. It consists of a central sulphur atom surrounded by four (equivalent) [[oxygen]] atoms. It occurs when sulphuric acid loses two hydrogens. If it only loses one, a [[hydrogen sulfate|hydrogen sulphate]] ion is made. {{chem-stub}} [[Category:Ions]] [[Category:Sulfur compounds]] [[Category:Oxygen compounds]]
