Study Notes
Purpose of the Experiment
- Demonstrates the concept of diffusion using potassium permanganate in water
- Allows observation of how substances naturally spread in a medium
Observation Details
- Initial addition of potassium permanganate causes a violet color to appear
- Color spreads throughout the water, indicating the movement of particles
Indication of Observations
- The violet color signifies that molecules are in continuous motion
- It illustrates the principles of kinetic molecular theory, where particles are always moving
Effects of Increased Concentration
- Adding a large amount of potassium permanganate would result in a more intense and rapid spread of color
- This would highlight the saturation point and the limits of diffusion in water
- Potentially leads to a quicker saturation in the surrounding water compared to a small amount
