Mixtures are classified into two types.Heterogeneous – not having a uniform
compositionWhat are the two types of
heterogeneous mixtures?

12.1
Mixtures are classified into two types.Heterogeneous – not having a uniform
composition1. Suspension
Large particles which can be caught by a filter Particles settle out upon standing May show the Tyndall Effect

Mixtures are classified into two types.Heterogeneous – not having a uniform
composition1. Suspension
Large particles which can be caught by a filter Particles settle out upon standing May show the Tyndall Effect Examples – Italian salad dressing, concrete, orange juice

12.1
Mixtures are classified into two types.Heterogeneous – not having a uniform
composition2. Colloid• Intermediate sized particles which are not caught by a
filter• Particles do not settle out upon standing• Does show the Tyndall Effect• Examples – fog, milk, whipped cream, butter

Mixtures are classified into two types.Homogeneous – having a uniform
composition with very small particles (solutions)

Mixtures are classified into two types.Homogeneous – having a uniform
composition with very small particles (solutions)
Particles will not be caught by a filter Particles do not settle out upon standing Does not show the Tyndall effect Examples – soda, bronze, air, tap water, sterling silver

12.1Solutions:Solute – substance that gets dissolved, usually
found in the smaller amount
Solvent – substance that does the dissolving, usually found in the larger amount
Electrolyte – aqueous solution composed of ions, will conduct electricity
Nonelectrolyte – aqueous solution not composed of ions, will not conduct electricity
