Sulphite, sulphide, and sulphate are three distinct chemical species that contain sulfur atoms. Here’s the difference between them:
**Sulphite: **A sulphite ion (SO32-) is a compound that contains one sulfur atom, three oxygen atoms, and a net charge of -2. Sulphites are commonly used as preservatives in food and beverages, as well as in the production of paper, textiles, and leather. Sulphites can also be found naturally in some foods, such as wine and dried fruits. Sulphites can cause allergic reactions in some individuals.

**Sulphide:** A sulphide ion (S2-) is a compound that contains one sulfur atom and two electrons with a net charge of -2. Sulphides are often found in minerals and can be formed by the reaction of elemental sulfur with other elements. Sulphides are important in the mining industry as they are often the primary ores of important metals such as copper, zinc, and lead.
**Sulphate: **A sulphate ion (SO42-) is a compound that contains one sulfur atom, four oxygen atoms, and a net charge of -2. Sulphates are common in minerals and are important constituents of soil and water. Sulphates can also be found in a variety of industrial and household products, such as fertilizers, detergents, and battery acid.
In summary, sulphite contains three oxygen atoms, sulphide contains two electrons, and sulphate contains four oxygen atoms. Each has its unique properties, applications, and uses.
