Diffusion experiment

Diffusion experiment  

Hello and welcome back to another blog today in chemistry we learnt about particle theory and diffusion.

Equipment-Petri dish, water, tweezer, a powder potassium permanganate 

Diffusion is when particles moving high too, low concentration.spread across an area diffusion occurs in liquids and gasses.

Aim- To see if it diffuses faster in hot or cold water.

Method-

1. Half fill your petri dish with cold tap water 
2. Place the petri dish on your work bench and allow the water to become settled.
3. Using the tweezers, place a single powder of potassium permanganate in the centre of the petri dish.
4. Observe for 5 minutes.
5. Repeat the experiment using hot water

Results:

In cold water- The potassium permangonate slowly spread around.

In hot water- The potassium permangonate spread faster than when it was in cold water.
