-In this video, we break down Classification of Matter (IB Chemistry Structure 1.1) so you can clearly understand the difference between pure substances and mixtures and apply it confidently in exam questions.
This topic forms the foundation of IB Chemistry. If you don’t fully understand how matter is organized, later topics like bonding and stoichiometry become harder.
We’ll cover:
What matter is (anything with mass and volume)
Pure substances: elements and compounds
Why elements cannot be broken down chemically
How compounds form in fixed ratios (e.g., H₂O, NaCl)
Why compounds have different properties from their elements
Mixtures: homogeneous vs heterogeneous
Physical vs chemical separation
Separation techniques (evaporation, distillation, chromatography)
Understanding the difference between chemical bonding and physical mixing is essential for scoring high in IB Chemistry Structure 1.
Whether you're revising for SL or HL, this lesson gives you the clarity you need.
