So I am going to talk about mixtures. ''
  • Suspension:

    The ingredients are (stirred) in. If left alone, they will settle out. The heavier ingredient will settle to the bottom. Filtration can separate the two ingredients. An example would be dirt mixed with water.

  • Colloidal:

    The size of the solute is smaller than in a suspension, but greater than in a solution (see below). The solute breaks down but remains as a clump of molecules and is smaller than the eye can see. Colloids are a bit unusual in that the solute is equally dispersed in the solvent as in a solution, but the solute does not completely break down. In many cases this is because something coats the bits of solute and prevents them from completely dissolving in the solvent. An example would be mayonnaise, jello or oobleck

  • Solution:

    ''The solute and solvent are dissolved and cannot be separated unless one of the ingredients changes state of matter. ie. distilation, (evaporating) or crystallation. An example would be salt and water.''

  • -
The two general types of mixtures, homogeneous and heterogeneous. A homogeneous mixture is all liquid or all solid, not bits of anything and example is apple juice, you do not see any particles of apples. A heterogeneous mixture is when it is mixed (such as a solid in a liquid, a liquid in a solid, or a liquid and gas), for example a smoothie, it can have pieces of the fruit that it was made of. You can also say that a homogeneous mixture is the same throughout and can be evenly mixed and a heterogeneous mixture can be easily separated.


salty water (dissolved)
sugar water (dissolved)
brewed tea or coffee
brass (a buttery yellow alloy of zinc and copper

  • Salad
  • Sandwich
  • Solids
  • Liquids
  • Gases
  • Beach sand
  • tree
  • basically anything that has multiple parts
I hope that this gave you a good idea about mixtures, what they are, and the types of mixtures.
