HOMOGENEOUS AND HETEROGENEOUS

• Mixture is a combination of two or more substances present in varied proportion.
• The gloves, face masks and disinfectant solution are some of the examples of mixtures because they were made using the combination of different materials.
• Halo-halo is an example of mixture.
• A mixture is a substance made by mixing other substances together.
• When two or more elements or compounds mix together, not necessarily in a definite ratio and do no interact chemically, then the resulting substance is known as a mixture.
• Each of the combine/mixed materials can be identified or distinguished from one another. This kind of mixture is called heterogeneous mixture.

  Each property of the materials in heterogeneous mixtures do not change.
• TWO TYPES OF MIXTURE:

  1. Homogeneous
  2. Heterogeneous
• Homogeneous mixture which contains substances that are evenly mixed and is uniform throughout in terms of physical appearance.
• Heterogeneous mixture which contains component substances that are usually easy to distinguish.
• Homogeneous Mixtures have uniform composition where the substances are evenly mixed. They are also called solution.
• The substance that dissolves or seems to disappear is called a solute while the one that dissolves is the solvent.
• We say soluble if the solid solute completely dissolved  in the liquid solvent and insoluble if it is not.
• Air is a example of gaseous solution.
• Metal alloys are examples of solutions in the solid phase.

   
• Ammonia water is a liquid solution made up of ammonia gas dissolved in water.
• There are three types of homogeneous mixtures.

   

  1. Solid Homogeneous Mixtures

  2. Liquid Homogeneous Mixtures

  3. Gaseous Homogeneous Mixtures
• Homogeneous mixture also appeared in gaseous state. This includes the air that we breath.
• Air is a mixture of oxygen, nitrogen, argon, carbon dioxide and other elements in smaller units.
• In heterogeneous mixtures or non-uniform mixtures, mixtures can be natural or man-made. Much of the food we eat are heterogeneous mixtures.
• Fried rice, chopsuey, pinakbet and fruit salad are some examples of Heterogeneous. We mix ingredients that go well together.
• Suspensions and colloids are the two forms of heterogeneous mixtures.
