Differentiate concentrated solution from diluted solution
Suspension
Heterogeneous mixture containing large particles that settle out when left undisturbed
Colloid
Stable mixture in which undissolved particles or droplets stay mixed in another substance. Particles do not dissolve, yet do not settle out.
Colloids
Show characteristics of both liquid and solid because the molecules that make colloids are either large molecules or clumps of molecules
Particles are large enough to scatter light
Emulsion
Suspension of two liquids that usually do not mix together. Requires an emulsifier to mix.
Blood is an example of Colloidal Suspension
Types of mixtures
Solution
Colloid
Suspension
Solution
Particles are small
Cannot be separated using filter paper
Cannot scatter light
Colloid
Particles are medium-sized
Cannot be separated using filter paper
Can scatter light
Suspension
Particles are large
Can be separated using filter paper
Can scatter light for fine suspensions
Tyndall effect is the scattering of light by particles in a colloid or some suspension
Brownian motion is the constant movement of particles in a mixture
A colloid is a type of mixture with properties intermediate between heterogeneous and homogeneous
A compound is a pure substance that contains two or more elements
An emulsion is a mixture of two or more liquids in which one is present as droplets, of microscopic or ultramicroscopic size, distributed throughout the other
