Types of Mixtures

Types of MixturesA mixture is a physical blend of two or more
substances.
Their composition varies (Air).
There are two types of mixtures: homogenous and heterogenous

Types of Mixtures Heterogenous mixtures
Is the type of mixture that is not uniform in composition. Has visibily different parts.
Granite, Chocolate Chip Cookies

Types of Mixtures Homogenous mixture Is the type of mixture that has a completely
uniform composition throughout itself. Does not have visibly different parts.
Seawater, Air

Homogeneous vs. Heterogenous

MixturesCommon Techniques for Separating Mixtures
Distillation – separates a mixture based on boiling points of the component.
Examples :saltwatercrude oil into gasoline and kerosene
Magnet – separates iron from other objects.
Centrifuge – spins and separates according to densities.

SolutionsSolutions are groups of molecules that are
mixed up in a completely even distribution. Hmmm. Not the easiest way to say it.
Scientists say that solutions are homogenous systems.

Soluteis the substance to be dissolved Example: (sugar).

SolventThe solvent is the one doing the dissolving Example (water)

SuspensionA mixture in which particles ofa material are dispersed through-out a liquid or gas but are largeenough that they settle out.
Particles are insoluble, so they DO NOT dissolve in the liquid or gas.
Particles can be separated using a filter. Examples: Salad dressing Medicines that say“shake well before use”

ColloidsA mixture in which the particles are
dispersed throughout but are not heavy enough to settle out.
Made up of solids, liquids and gases.Examples :
Mayonnaise Stick deodorant milk
