Description: Uses photographic polarization techniques to visualize the homogeneous mixing of a liquid with a solid, gas, or another liquid. Demonstrates the more common test one can perform to differentiate between a solution and other mixtures. Shows that the speed with which a solid dissolves is related to its surface area, temperature and the effect of stirring., What is a solution? A mixture of lead oxide and water leaves a residue as it passes through a filter, but a solution of copper sulfate passes through unchanged. What does this test indicate about the size of particles in the copper sulfate solution? Why does a light beam scatter as it passes through some mixtures and not others?
