Lab: The Effect of Concentration on the Rate of Diffusion

PURPOSE: This experiment will explore the concentration gradient by measuring the rate of diffusion in a number of theoretical cells. The objectives for this lab are: (1) To define concentration gradient, (2) To explain experimental data concerning different concentration gradients, (3) To complete a data table and prepare a graph to illustrate the data, and (4) To apply information from this experiment to other related problems.
