The document provides instructions for an experiment examining the rate of diffusion of acids and bases into water using Vernier probes. Students are given samples of varying molarity to test, including 1M and 2M HCl and NaOH, as well as water. They set up the probes to collect pH data over 5 minutes and graph the results. From the graphs, they determine the slope and relate how molarity affects diffusion rate, and whether each sample created a hypotonic, hypertonic, or isotonic solution when mixed with water.
