Dilution Experiment

Dilution Experiment

Aim:

I want to investigate how to dilute a solution

Dilution:

Dilution is the process of reducing the concentration of a solute in solution, usually simply by mixing with more solvent

Equipment:

Test Tube Rack

Test Tubes

10mL measuring cylinder

Method:

1.Fill measuring cylinder with 10mL of water

2.Add 10mL of water to a test tube

3.Add 9mL of water to 5 more tests tubes.

4.Add a small spatulaful of Potassium Permanganate to the first 10mL test tube of water

5.Add 1mL of the dark purple Potassium Permanganate into the second test tube.

6.Add 1mL of the dark purple Potassium Permanganate into the second test tube.

7.Add 1mL of the third test tube into the fourth test tube.

8.Add 1mL of the fourth test tube into the fifth test tube.

9.Add 1mL of the fifth test tube into the sixth test tube.

Results:

Discussion:
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.
