Dilution

Aim

I want to investigate how to dilute a solution.

Equipment

-Test Tube Rack.
-Test Tubes.
-100ml Measuring Cylinder.
-Dropper.

Method

-Fill measuring cylinder with 10ml of water.
-Add 10ml of water into a test tube.
-Add 5ml of water to 5 more test tubes.
-Add a small spatula of Potassium Permanganate to the first 10ml  test tube of water.
-Add 5ml of the water mix with the chemical from the first test tube into the measuring cylinder.
-After that add the 5ml of water mix with the chemical into the second test tube.
-Repeat to the remaining 4 test tubes.

Results




Discussion

-The first test tube went dark purple.
-As we poured 5ml from each test tube into the next test tube, the colour became lighter and lighter.
