Classifying Matter: Elements, Compounds, Mixtures (Chemistry)
Practice Tests available at http://bit.ly/CHEMTESTS
Sign up to Socratica Chem Club for your free Classifying Matter handout: https://bit.ly/FreeChem2
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.
You can jump to sections in the video here:
0:00 What is Matter?
0:39 What are Pure Substances?
1:25 Flowchart to Classify Matter
2:11 What’s the difference between Elements and Compounds?
3:08 The Law of Constant Composition aka the Law of Definite Proportions
4:58 What are Mixtures?
7:03 Homogeneous Mixtures vs Heterogeneous Mixtures
9:25 Pop Quiz - classify these materials!
11:37 Challenge Exercise - separate sea salt out of beach sand

We made a FREE HANDOUT with the Classifying Matter flowchart for you. Sign up for the Socratica Chem Club to get your free handout: https://bit.ly/FreeChem2
If you're studying for a TEST on the States of Matter and Phase Diagrams, we made a practice test for you with 50 questions and a complete answer key with explanations. You can purchase our practice tests on our website here: http://bit.ly/CHEMTESTS

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 then 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. She is now the head writer and producer of Socratica Studios.
