Chemistry is the science concerned with the study of the composition, structure and properties of matter, with a particular emphasis on its chemical reactions and bonds.

Severus Snape mentioned it in his introduction to Harry Potter's first class in 1991. Chemistry involves the mixture of chemicals and certain processes to get the desired end product. Severus Snape was known to like chemistry, and in his childhood he used to play with his chemistry set, according to Sirius Black.
