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 Procedure and Observations: Procedure- Observations- 1. Get beackers 1. Mixture 1 is very clear, and 2. Examine mixtures, record colorless. Observations. 2. Mixture 2 has a foggy, glossy ...
