Osmosis – A Special Type Of Diffusion
- 1. Osmosis – a special type of diffusion Lesson objective I will know what osmosis is
- 3. Results Solution Mass Before (g) Mass After (g) Mass Difference (g) 0.3M sucrose 1.0M sucrose Distilled water
- 4. Diffusion is the spreading of the particles of any substance in solution, resulting in a net movement from a region where they are of a higher concentration. (end up with even spread of particles)
- 7. Osmosis Dilute Solution Concentrated Solution Net movement of water The water will move into the concentrated solution until both are equal. The solutions are said to be ISOTONIC Solute Water
- 9. Illustrate with diagrams to describe how water moved across a semi-permeable membrane in each case
- 10. Conclusion No net movement - Isotonic Potato loses mass - flaccid Potato gains mass - turgid Potato 0.3M Potato 1.0M Potato Water Sucrose Water
