Tyndall lab and density lab

Introduction: The purpsose of the experiment is to classify mixtures using the Tyndall effect. Mixture 1 is a solution before and adter filtration. Mixture 2 is a colloid before and after filration. Mixture 3 is a solition before and after filitration. However, Mixture 4 before filtration was a suspension and then after filtration it transformed into a colloid.
Hypothesis:
Mixture 1- solution
Mixture 2- Colliod
Mixture 3- Solution
Mixture 4- suspension

Materials and equipment:

· The 4 unknown mixtures
· 40 ml of each solition
· Filter paper
· Beakers
· Funnels
· Laser beam
