Description
describe the physical property used for the separation
Chemical versus Physical Separation
During the video various techniques will be shown that allow someone to easily separate mixtures.
For each of the following techniques:
- Describe the physical property used for the separation.
- Describe the method
- Give one example of when the technique could be used.
Centrifugation
Chromatography
Filtration
Distillation
Decantation
Magnetic Separation
There are other techniques that are not included in this video. For the methods listed below, use the internet to research information on each one. Answer the same three questions you did for the methods described in the video.
Evaporation
Decanting
Sieving
Apply what you have learned:
In a 500 mL plastic container is a mixture containing sand (about 250 mL), ‘dead’ matches, small pebbles and steel paper clips mixed evenly.
Your task is to separate the four parts of the mixture: Sand, ‘dead’ matches, small pebbles, and steel paper clips.
Materials available:
Water
Magnets
Paper filter
Wire filter/sieve
Devise and write up a step by step plan of a method to separate the four parts. You will need to think about the properties of each part of the mixture that will make the separation possible.
