Discussion:

(Use the questions provided below to assist you in writing your discussion in paragraph format. DONOT write the questions in your lab book.)

1. What is diffusion?

2. What is the concentration gradient?

3. Explain what took place in terms of concentration gradient in the experiment.

4. Explain what caused the movement the potassium permanganate particles and how it spread in the beaker.

5. What was the distribution of particles at the end of the experiment?

Conclusion:

(State the outcome of the experiment based on the aim and give reason to support based on the results.)
