Dilution series ;)

Aim: 

To make a dilution series to investigate the concentration

Equipment:

A potassium permanganate crystal
Six large test tubes
Tweezers
A plastic transfer pipette
A test tube rack
10 mL measuring cylinder.

Method:

1. Place the six test tubes rack label the rack with numbers 1 - 6
2. Using the measuring cylinder, fill the test tube 1 with 10 ml of water. Fill the remaining tube with 5 ml of water.
3. Using your tweezers, add a single crystal of potassium permanganate to test tube one
4. Gently has the test tube until the crystal has dissolved
5. Using the transfer pipette, carefully remove exactly 5 ml from test tube one and pour it into test tube two.
6. Rinse the transfer pipette thoroughly to ensure no purple solution remains.
7.  Gently shake test tube two and repeat the transfer process, transferring exactly 5ml of solution f
