Making a Dilution Series

Aim: To make a dilution series to investigate concentration.

Equipment: A potassium permanganate crystal, six large tes tubes, tweezers, a plastic transfer pipette, a test tube rack, 10 mL measuring cylinder.

Method: 1. Place the six test tubes in a test tube 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 test tubes with 5ml of water
3. Using your tweezers, add a single crystal of potassium permanganate to test tube 1.
4. Gently shake the test tube until the crystal has dissolved.
5. Using the transfer pipette, carefully remove exactly 5 ml from test tube 1 and pour it into test tube 2.
6. Rinse the transfer pipette thoroughly to ensure that no purple solution remains.
7. Gently shake test tube 2 and repeat the transfer process, transferring exactly 5 ml of solution from test tube 2 to test tube 3.
8. Rinse the pipette again and repeat the transfer process for test tubes 4, 5 and 6.

Results: Our experiment went well and the water went lighter and lighter. Our experiment was a success.

Investigating Solubility

SOLUBILITY EXPERIMENT

Aim:

To investigate the solubility of baking soda, table salt and copper oxide to see which is the most soluble

Equipment:

100mL beaker, 100mL measuring cylinder, salt, baking soda, copper oxide, stirring rod, spatula.

Method:

1. Fill the beaker with water
2. Add a spatula full of baking soda.
3. Stir the solution until it dissolves.
4. Repeat step 2 and 3 until no more will dissolve.
5. Record how many spatula fulls were added.
6. Repeat the experiment with salt and copper oxide.

2 full spatula of baking soda 

My experiment failed because the water did not turn into a clear water.

Making a Copper Sulfate Salt

MAKING A COPPER SULFATE SALT

Aim: To produce copper sulfate salt by reacting copper oxide with an acid

Equipment: Copper oxide powder, dilute sulfuric acid, measuring cylinder, 2x 100mL beakers, bunsen burner, tripod, gauze mat, funnel, filter paper, thermometer, spatula, evaporating basin, stirring rod.

Method:

1. Add 20mL of sulfuric acid to a 100mL beaker. Heat to 70degrees. Turn off your bunsen.
2. Once heated, use a spatula to add pea-sized portions of copper oxide. Stir for 30secs
3. Repeat step 2 until no more dissolved.
4. Fold filter paper and place in the funnel. Place the funnel in the second beaker.
5. Make sure your first beaker is cool enough to hold and then pour it into the funnel. Gently swirl and allow to filter through.
6. Rinse the beaker and fill with 50mL of water and place on a tripod. 
7. Place evaporating basin on top of the beaker and pour some solution in.
8. Gently heat until the solution has reduced by half.
9. Take off heat and allow to cool.

Results: The results of our experiment was a failure because not that much crystal formed and there is only a bit of crystal. (solvent) liquid evaporated and did not form crystals.
