Diffusion of Potassium Permanganate in Water

The diffusion of potassium permanganate in water is an evidence often used to show that matter is made up of atoms. Why? The crystalline structure dissolves on contact with water and the movement of the particles in water can be observed due to its bright purple colour.

I still don't know how to write up this lab😭😕

this was really helpful for my lab. :)

This video was very helpful. Thank you, have a nice day

What would you say is the observation for this?

My bio teacher linked this vid for the lad report, very help full

Hi Mrs C. Williams, can it be concluded that gases take a shorter period of time than liquids, to diffuse, due to there weaker inter-molecular forces.

i just wanted to know what would happen if we heat that solution

[britneygrey]

Is it cold water or room temperature water?

[zazabird]

Why do you leave the water to settle before adding the crystal?

[coleenclarke]

Why was it important to leave the water completely still before the crystal was put in ?

How do I get potassium permanganate crystal?
