New cards
2

To get rid of Solvent in a mixture we use...

Evaporation (solvent evaporates)

New cards
3

Distillation

A process separates the Solvent substances in a solution based on their boiling points. (the solvent is captured in a conical flask)

New cards
4

What is a boiling point?

The temperature when a solvent substance evaporates. turns into a gas.

New cards
5

condensing point

the temperature at which the vapor pressure of the solvent is the same as the external pressure.

New cards

What is a solute?

A substance that is dissolved in a solvent

New cards
7

What is insoluble?

Can't be dissolved in a solvent

Filtering, Decanting, Seiving and Separating funnel.

Matter that settles to the bottom of a liquid.

New cards

What is a colloid?

A mixture containing small, undissolved particles that do not settle out. Example is Paint

New cards
19

Emulsion

A colloid whitch is spread evenly through another.

New cards
20

Controlled variable

something that you can controll in an experiment.

New cards
21

Independant variable

a variable that stands alone and isn't changed by the other variables you are trying to measure or find out.

New cards
22

Dependent variable

is the effect that the indipent variable. example the sunlight is the indipent variable and the groth of the plant is the dependant as it is the effect of the sunlight.
