Diffusion

First experiment we did was simple.

The aim of the experiment was to determine what made the potassium manganate (VII) turn the water, purple.

You just need to add a few drops of potassium manganate (VII) into a beaker full of water.

What made the water turned purple?

The answer is diffusion occured.
Diffusion is the spread of particles through random motions from a region of high concentration to a region of low concentration.

And this is how diffusion looks like when potassium manganate (VII) is added into a beaker of water.

Another important thing to remind you all.

POTASSIUM MANGANATE (VII) IS PURPLE COLOUR. :)

Science and Maths Club of SMK Seafield 2012.

We may be a small group, but we are like a family conducting and discovering new things by carrying out experiments. And a certain reaction occurs every time a meeting is conduct. Laughter. :)

The next post will be about the activities, I mean EXPERIMENTS that we carried out.

adopts the hypotheses as they were demonstrated propositions.'
