Separating Mixtures Part 1

Good morning, class. We will use our time today for your group presentations. Group 1, please come in front when you're ready.
Good morning, everyone. We are group 1 and today we will be sharing 8 methods of separating mixtures.
First, we have decantation.
Decantation is the process of pouring a liquid from one container to another to separate the liquid from solids or denser liquids. The solids or denser liquids are left at the bottom of the original container .
Next, we have filtration.
Filtration is the process of separating solids from a liquid by pouring the mixture through a porous material such as filter paper. The solid particles are left on the filter paper while the liquid passes through and is collected in a container at the bottom of the filter. Thus, achieving separation.
The 3rd method is centrifugation.
As you can see, centrifugation uses centrifugal force to separate particles from a solution, wherein, the denser particles settle at the bottom of the container.
For the next and 4th method, we have distillation.
Distillation uses both evaporation and condensation to separate liquids that have different boiling points. The liquid with the lower boiling point evaporates 1st, passes through a tube where it cools off, condenses back into its liquid state, and is collected in another container at the other end of the tube.
