Finding the Activation Energy Between Hydrochloric Acid an Sodium Thiosulfate

III. For observation 1 and 2, pour 1 cup of water into a pan and place on stove on high heat. For observation 2 add

In the lab we filled the first beaker up with water. Then we took a pipet (filled with the liquid) and dropped water droplets onto the

1. Fill the graduated cylinder nearly to the top with water, with a tall glass tube open at both ends (the water level with act as the closed end).

Place the beaker on the hot plate, place the thermometer in the beaker and set the hot plate to 5oC.

Write a balanced chemical equation for each reaction #1-8. Classify each reaction using the information provided in the

C6H12O6 + 6O2 → 6CO2 + 6H2O + 686 kilocalories of energy/mole of glucose oxidized

Finally disconnect the tubing and remove the filter paper collecting the solid that has formed on it then allow it to dry

4.Measure 35mL of warm water and add them into each of the 4 test tubes at about roughly the same time. It is essential that the water is warm. Do not seal the test tube.

2. Fill a flask with pure water (0% sugar), another with 0.2M water, another flask with 0.4 M water, and another flask with 0.8M water.

- Get 5 50mL beakers and fill the first one with 30 mL of water

4. Remelt the contents of the tube and add the counterpart component based on the given schedule. Ask the demonstrator to adjust the cooling water between mixtures. During the experiment, record and plot the data obtained for all mixtures listed. The experiments are stopped as follows:

4) Try and propose a mechanism for the reaction using the orders of reaction taking into account the iodine, propanone and sulphuric acid.

To keep this a fair test I have made sure that the acid used is the

Once the range is obtained, remove the thermometer and beaker. Pour out the hot water and allow both the thermometer and the beaker to cool. Once cool, repeat the previous steps with the second compound, tetradecanol. At the conclusion of the second experiment, repeat the steps for a third and final time using an equal mixture of both compounds. Be sure to record the melting point range for all three experiments.

The procedure was performed as follows: For run 1, 20cm3 of acetone, 10cm3 of sulphuric acid and 145cm3 of water was added to a conical flask. 25cm3 of iodine was then added to this solution which started the reaction and immediately, 20cm3
