  1. Exploring Pure Substances & Mixtures Ch. 11 Lesson 1 Mr. Breeden

  2. Mixtures vs Pure Substances • A Mixture is two or more substances that are together in the same place, but not chemically bonded. • A Pure Substance is a single kind of matter that has a specific make up

  3. Mixture Chocolate Milk- milk, chocolate, sugar, etc. Pure Substance Water- H2O

  4. Pure Substances • Pure Substances can’t be separated easily (sometimes they can’t be separated at all • Example- H2O, you can’t separate the hydrogen from the oxygen very easily because they’re chemically bonded • Anything that is chemically bonded completely will be considered a pure substance • C169 723H270 464N45 688O52 243S912 is considered a Pure substance

  5. Mixtures • Mixtures are two or more substances that are together, but not chemically bonded • Example- NaCL+H2O, Saltwater, can be separated many ways • Salt and Water are both pure substances, but when mixed together they’re considered a mixture

  6. Pure Substances & Mixtures • Pure Substances are rarely found in nature. Most of the time they’re mixed with something • Even though Gold is an element (Au), it is found as Gold ore in nature

  7. Practice- Pure Substance or Mixture? • Hydrochloric acid- H20 + Cl2 • Ammonia- NH3 • Bleach- NaOCl • Ammonium Chloride- NH3 + HCl

  8. Heterogeneous- you can see the different parts Homogeneous- so evenly mixed that you can’t see the different parts

  9. Separating Mixtures • Compounds (pure substances), like H2O, are very difficult to separate into elements • Mixtures are usually very easy to separate. Like Saltwater. We can easily separate the salt (NaCl) from the water (H2O)

  10. Physically Magnetism Filtration

  11. Distilling Extraction Evaporation
