Aim:
I want to investigate how to dilute a solution.
Equipment:
Test Tube Rack
Test Tubes
10mL measuring cylinder
What is dilution?
Dilution is a process where you dilute liquid or a solution.
Method
Fill measuring cylinder with 10mL of water
Add 10mL of water to a test tube
Add 9mL of water to 5 more tests tubes.
Add a small spatulaful of Potassium Permanganate to the first 10mL test tube of water
Add 1mL of the dark purple Potassium Permanganate into the second test tube.
Add 1mL of the second tube into the third test tube.
Add 1mL of the third test tube into the fourth test tube.
Add 1mL of the fourth test tube into the fifth test tube.
Add 1mL of the fifth test tube into the sixth test tube.
Results
The first test tube went a dark purple colour.
As we poured 1mL from each test tube into the next test tube, the colour lightened each time.
