Our aim was to make a dilution series to investigate concentration.
What equipment we used we used Potassium permanganate crystal,six large test tubes,tweezers,a plastic transfer pipette,a test tube rack ansd a 10 mL measuring cylinder.
1. Place the 6 test tubes in a test tube rack. Then label them numbers 1-6.
2. Using the measuring cylinder, fill test tube 1 with 10 mL of water. Then fill the other five test tubes with 5 mL of water.
3. Using your tweezers, add a single crystal of potassium permanganate to test tube one.
