You're on a roll — Question: Describe the experiment demonstrating diffusion in liquids using a potassium permanganate crystal, including the initial setup, observation, and conclusion, as detailed in the notes. Answer: The experiment demonstrating diffusion in liquids using a potassium permanganate crystal is as follows: Initial Setup: A crystal of dye (potassium permanganate) is carefully placed at the bottom of a beaker containing water, ensuring it is not overly disturbed. Observation: When the potassium permanganate crystal is placed in the water, it dissolves. Initially, the permanganate ions are concentrated in the area where the crystal was placed. Over time, a net movement of permanganate ions occurs throughout the beaker of water. Process: The dye molecules (solute) and water molecules (solvent) move randomly. The dye molecules move from an area of high concentration (where the crystal dissolved) to an area of low concentration. Conclusion: The permanganate ions continue to move from the area of high concentration to the area of low concentration until they are evenly distributed throughout the water, resulting in a uniformly colored solution. This demonstrates the principle of diffusion in liquids.
