Applications of chemistry to reagents, reactions and processes of everyday life. Use this tag for question on chemistry in an out-of-laboratory/class context. DO NOT use this tag merely because the question is about simple chemistry.

This tag can be applied to questions regarding the chemical processes behind common reactions observed in the day-to-day lives of people working outside laboratory or industrial settings. Also acceptable are questions regarding the chemical composition of everyday "household" items, e.g. cleaning supplies, plastics, batteries, food and drink, and common fuels such as gasoline or natural gas.

Chemistry is central to virtually all aspects of modern living in industrialized nations. While the general definition of chemistry as "the study of different types of atomic elements, their reactions and products" makes it applicable to every aspect of the existence and functioning of the universe, the more limited common connotation of a "chemical" as being "some created or extracted substance not typically seen in this form in nature" typically limits the "everyday" aspect of chemistry to those types of "artificial" substances seen in the day-to-day lives of people not directly associated with the field of study. Even then, virtually every consumer item currently available for sale has been improved or even made possible through the targeted development of "artificial" chemical substances with desirable properties for the intended use of the end product.
