Ultimate List of Chemical Compounds and Their Common Names And Formulas

We often refer to many household chemicals by their common names. For instance, you will rarely find a person asking you to give him dihydrogen oxide (water) when he is thirsty or to pass him sodium chloride (salt) at the dinner table!

However, it is important to recognize that common names are not only inaccurate but also tend to vary from one place to another.

This means that the only reliable way to name chemicals is using a standardized chemical nomenclature.

A standardized nomenclature ensures that a chemical name leaves no ambiguity as far as the chemical nature of a compound is concerned. In other words, it gives an accurate description of a chemical compound or substance’s composition. 

Besides, using scientific names ensure that each substance has a single name (though there are cases where alternative names may be acceptable).

The world-accepted format for chemical nomenclature has been established by the International Union of Pure and Applied Chemistry (or IUPAC).

The long and the short of it is that don’t assume that you know the chemical composition of a substance on your kitchen cabinet based on its common name.

To keep you up to date, here is a comprehensive list of chemical compounds and their common names and formulas:
