|
Suspension
|
a mixture in which particles can be seen adn sasily separated by settling or filtration
|
pepper in water
italian salad dressing orange juice with pulp |
|
|
Solution
|
a well mixed mixture that has the same properties throughout
|
salt water
air brass |
|
|
compare the size of solution particles to the size of suspension particles
|
The size of particles in a solution are smaller than those in a suspension
|
|
|
|
Solvent
|
A part of the solution present in the largest amount
A solvent dissolves other particles |
solution salt water/ solvent water
solution air/ solvent nitrogen solution brass/ solvent copper |
|
|
What is considered the universal solvent?
|
water
|
|
|
|
Solute
|
a subsstance that is present in a solution in a smaller amount and dissolved by the solvent
|
salt is the solute in salt water
oxygen and other gases are the solutes in air |
|
|
How do solutes affect boiling points? Why?
|
when solute particles are added to a solvent fewer particles are exposed to the surface. Therefore, fewer escape into the air causing the boiling point to rise
|
|
|
|
Colliod
|
a mixture with small undissolved particles that do not settle out
|
Gelatin
Mayonnaise shaving cream |
|
|
How do the size of the particles of a colloid compare to the particles of a solution?
|
The particles of a colliod are smaller than those of a suspension.
|
|
|
|
How do the particles of a colloid affect light?
|
Particles in a colloid scatter light beams
|
|
|
|
How do solutes affct freezing points? Why?
|
Solute particles make it harder for water molecules to form crystals, therefore, solutes lower the freezing point of liquids.
