What Is Sulphate?
Sulphate is a chemical ion composed of one sulfur atom and four oxygen atoms, represented by the chemical formula
Definition
Polyatomic Ion: An ion that consists of two or more atoms bonded together, which carries a net charge.
Definition of Sulphate
The sulphate ion features a central sulfur atom surrounded by four oxygen atoms in a tetrahedral configuration. Notably, the tetrahedral arrangement gives sulphate its unique chemical properties.
In terms of structure, each sulfur-oxygen bond is covalent, meaning that the atoms share electrons. The tetrahedral configuration means that the angle between the sulfur and any two oxygen atoms is approximately 109.5 degrees, which is typical for groups of four atoms bonded to a central atom.
Definition
Covalent Bond: A type of chemical bond where atoms share pairs of electrons.
Chemical Formula of Sulphate
The chemical formula for sulphate is
- S: Represents the sulfur atom.
- O: Represents the oxygen atoms.
- 4: Indicates that there are four oxygen atoms.
- 2-: Signifies a charge of negative two, showing that the ion is capable of combining with other elements.
Examples
For instance, if sulphate combines with sodium, it forms sodium sulfate with the formula
