Movement Of Particles

Question 1

What is the definition of diffusion?

Answer 1

gradual movement of particles from an area of high concentration to an area of low concentration through a semi-permeable membrane

Question 2

Explain how to set up an Potassium Magnate (VII) & Water Experiment to show how diffusion takes place.

Answer 2

1) Take beaker of water + add Potassium Magnate (VII) to bottom, purple colour slowly spread to fill beaker

2) particles of Potassium Magnate (VII) are diffusing out among particles of water

3) Random motion of particles in liquid causes purple colour to be easily spread out through water
