1. In chemistry and particularly in regard to microscopy, precipitation is the alteration of a liquid solution (usually a mounting or staining agent) into a hardened form. This can be caused by a chemical reaction inducing the hardening of one or more chemicals. A chemical can also precipitate from a fully liquid form into a gradually hardening form as it dries and becomes more and more dense. Precipitation is the creation of a solid in a solution or inside another solid during a chemical reaction or by diffusion in a solid. When the reaction occurs in a liquid solution, the solid formed is called the ‘precipitate’. The chemical that causes the solid to form is called the ‘precipitant.’ A common example of precipitation occurs when KOH begins drying and forms crystals on the glass slide.
