The Catalase Lab Essay Example for Free

The Catalase Lab Essay Conclusion- The Researcher’s hypothesis, â€Å"If more catalase is added then more oxygen (kPa) will be produced in a faster rate because there is more catalase to react upon† and â€Å"if less catalase is added then less oxygen (kPa) will be produced in a slower rate because there is less catalase to react upon.† It was supported by the data obtained because the data obtained showed us that the data of the 5 filter paper obtained showed a faster reaction rate and there was an 85. 5 kPa increase (See Analysis). The data of the 1 filter paper obtained showed a slower reaction rate of 12 kPa average increase. Based on the regular result of the 2 filter paper that showed a reaction rate of 22 kPa average increase, that shows that the hypothesis was supported. In the researcher’s opinion, the experiment went well and got the results that we expected. The reason we got the result that we did was because the hydrogen peroxide had more catalase to break down which caused more bubbles which creates oxygen. More catalase, more oxygen that is produced by the breakdown of the catalase. It’s shown by the data that 5 filter papers produced more oxygen (85.5 kPa) than the 2 filter paper (22 kPa) and the 1 filter paper produced less oxygen (12 kPa) than the 2 filter paper. During the experiment, there were couple of errors that caused our data to be inaccurate that we could of improved on. One of our errors was during the 2 filter paper trial. During one of the trial, around the 5-10 second period, I let out a little gas out of the test tube which lowered the kPa pressure. It’s shown on the graph that the pressure has dropped around the 5-10 second range by 4 kPa so that made the result inaccurate. This affected our average of the 2 filter paper average gas pressure. This could have been prevented if I didn’t loosen up the stopper which lead to the escape of gas in the test tube. Another error that we had that we can improve on is the constant pressure that is put onto the stopper on the test tube to measure the gas pressure. It’s shown on the graph that trial 1 2 of each 1,2, 4 filter paper is not consistent showing the difference between trial 1 trial 2 This can affect the kPa average which shows inconsistency. This could have been prevented if we didn’t put so much pressure on the stopper on 1 trial and then not put as much pressure on the stopper on the next trial. Research shows that this can help determine how much oxygen can be produced is to get the hydrogen peroxide to react to the catalase. Research shows that the different environment can affect the production of oxygen in the experiment. More catalase leads to more oxygen production and less catalase leads to less oxygen production. This can be used to determine how chemical breaks different things down and what it produces in the end. Also shows that different environment can change results of different chemical reactions. Hydrogen Peroxide is used on cuts to clean out debris. The Hydrogen Peroxide bubbles because the catalase in the blood is in contact with the peroxide which bubbles out the debris.
