Aim: To dilute potassium permanganate to see how dilution works.
Method: we had to put 10 mls of water in the first test tube then a little bit of potassium permanganate.
Then we had to take 5 mils of that and add it to the 5 mls of water in the next test tube then do the same until it got to the end and it was barely coloured anymore.
Equipment:
1.potassium permanganate.
2. water.
3. test tubes and racks.
4. Pipette.
Results:
Discussion: They slowly got lighter and more dilute, you could clearly see the colour change.
