  2. Mixtures Heterogeneous materials - can see two parts Homogeneous materialscan see only one thing - one set of properties Homogeneous mixtures They’re mixed together so well you only see one thing – it looks pure but it isn’t Pure substances You can only see one thing because there is only one kind of particle in it. Matter Solution

  3. Mixtures • a combination of two or more substances that do not combine chemically • remain the same individual substances • can be separated by physical means • Two types: • Heterogeneous • Homogeneous Based on the prefixes “hetero” and “homo,” what do you think are characteristics of these two types of mixtures?

  4. Heterogeneous Mixture • “Hetero” means different • consists of visibly different substances or phases (solid, liquid, gas) Example: Notice the visibly different substances Trail Mix

  5. Homogeneous Mixture • “Homo” means the same • has the same uniform appearance and composition throughout; maintain one phase (solid, liquid, gas) • Commonly referred to as solutions Example: Notice the uniform appearance Salt Water

  6. Solution • a mixture of two or more substances that is identical throughout • can be physically separated • composed of solutes and solvents Salt water is considered a solution. How can it be physically separated? the substance in the smallest amount and the one that dissolves in the solvent the substance in the larger amount that dissolves the solute Iced Tea Mix (solute) Water (solvent) Iced Tea (solution)

  7. Solubility • the amount of solute that dissolves in a certain amount of a solvent Solublemeans it can be dissolved in a liquid What do we call things that are not soluble? Insoluble means it can't be dissolved in a liquid
