11.5 Colloids
The term "colloid"—from the Greek words kolla, meaning "glue," and eidos, meaning "like"—was first used in 1861 by Thomas Graham to classify mixtures such as starch in water and gelatin.Many colloidal particles are aggregates of hundreds or thousands of molecules, but others (such as proteins and polymer molecules) consist of a single extremely large molecule.
