In Chemistry Class, almost always we are talking about reactions involving PURE SUBSTANCES. But in the real world, we rarely stumble upon pure samples of anything! Almost everything we come in contact with is a mixture, rather than a pure element or compound.
Chemists classify matter according to how pure the sample is. This means you need to learn to distinguish between the following: pure substances (elements or compounds) and mixtures (homogeneous or heterogeneous). We’ve created a flowchart to make this kind of classification easier.

About our instructor:
Kimberly Hatch Harrison received degrees in Biology and English Literature from Caltech before working in pharmaceuticals research, developing drugs for autoimmune disorders. She continued her studies in Molecular Biology (focusing on Immunology and Neurobiology) at Princeton University, where she began teaching as a graduate student. Her success in teaching convinced her to leave the glamorous world of biology research and turn to teaching full-time, accepting a position at an exclusive prep school, where she taught biology and chemistry for eight years. Kimberly co-founded Socratica Studios.
