Solution

a mixture containing a solvent and at least one solute and has no chunks completely disolved

insoluble solute cannot dissolve at all

cannot dissolve at all so can’t become a solution it would be a suspension

what dissolves well in a nonpolar solvents

ionic and polar compounds

For liquid solution what do ionic and polar compounds usually dissolve in?

polar solvents

What do nonpolar compounds usually dissolve in?

nonpolar solvents

Do Ionic compounds still conduct electricity if they are dissolved in water?

yes

\
What happens to the solubility of a fans in a liquid solvent ad the pressure increases?

it increases

Do ionic solution conduct electricity?

yes

What do solutes do to the boiling point of the solvent?

Raise it

What do solute do to the freezing point of the solvent?

raises it

a mixture is classified as a solution, colloid, or suspension based on what?

the size of its largest particles

Concentration

the amount of solute per volume of solvent in a solution

Solvent

the part of a solution usually present in the largest amount

Solute

the substance that is dissolved by the solvent

Colloid

Small undissolved particles: If you can’t see the particles but are there

What is the universal solvent?

Water

Suspension

a mixture in which particles can be seen and easily separated by settling or filtration

dilute solution

a mixture that has only a little solute dissolved in a certain amount of solvent

concentrated solution

a mixture that has a lot of solute dissolved in the solvent

How can you change the concentration of a solution?

by adding a solute or by adding/removing a solvent

solubility

a measure of how much solute can dissolve in a solvent at a given temperature

what factors affect solubility?

pressure, the type of solvent, and temperature

saturated solution

when you’ve added so much solute that no more disolves

How do solutions form?

when particles of the solute separate from each other and become surrounded by particles of the solvent

2 examples of a colloid

fog, shaving cream, milk, smoke, ice cream

2 examples of a solution

water and salt, iced tea

2 example of a suspension

mint chip ice cream, rocky road ice cream
