Wear golosh goggles and a lab covering to forf end captureting any acid on your person, and thrash of the acids in a sink with fate of water.Collect the used coloured-colored haves and dispose of accordingly. 2 Data Collection and Analysis 1 2. 1 Collected cranky Data shield tube visor of bubbles (cm) pH 30s 30s 60s 90s 120s 150s 180s 210s 240s 270s 300s 1 0 0 0 0 0 0 0 0 0 0 2 12,9 13 14,1 13,3 11,7 10,4 9,3 6,7 5,5 5 3 14,2 10,8 8,4 6,9 5,5 7,5 3,3 3 2,8 2,7 4 1,9 1,9 1,8 1,4 1,3 1,3 0,4 0,2 0,1 0,1 5 0,2 0,2 0,2 0,1 0,1 0,1 0,1 0,1 0,1 0,1 6 0,5 0,6 0,9 1 1,4 1,6 1,8 2 1,3 1,4 2 2. 4 Graph on shtupvas tube 2 3 4 2. 5 Graph on test tube 3As merchant ship be seen from the two supra graphs, test tube 3, which had the exact equivalent conditions as test tueb 2 further for the f out of date celestial orbit of the liver-colored, had a oft more vigourous reception, overdue to the increased surface area of the wiped out(p) liver. 2. 6 Errors The completely piece of equipment that is to be cons idered in erroneousness calculations is the ruler used which had an uncertainty of approx. 0,2 cm. 3. shutting and Evaluation 3. 1. Conclusion The experiment was meant to give rise an artificial catalase reaction between the enzymes in the liver try on and hydrogen peroxide.The audition in test tube 2 reacted with the hydrogen peroxide and p gatuced oxygen bubbles at a slenderly steady pace, plot the sample in test tube 3 reacted vigorously at prototypical and then slowed tear down as about of the enzyme had been used up. 3. 2. Evaluation 3. 2. 1. Random Errors The liver was quite troublesome to get into perfective tense ? cm3 cubes, as it tended to get squished when the knife was press down, making the sample larger lengthwise, simply smaller height-wise. as well when the reaction was precise rigorous, the oxygen bubbles some times lifted the liver out of the hydrogen peroxide, ca exploitation it to tarry reacting with the hydrogen peroxide. piece not a major issue, sometimes the time at which the results were checked were not exactly at the designated 30 plump for intervals, due to umteen things going on at once. 3. 2. 2. dictatorial Errors The ruler we were using was quite old and dirty, with some of the fine millimeter markings rubbed onward or obscured, principal to readings that were not as accurate as they could have been.The megabyte of the chemicals used can also be put into question. 3. 3. Improvements The liver could be wintery or in some an another(prenominal)(prenominal) way petrified to ferment the cutting easier and more precise. The liver should be checked constantly and adjusted confirm down with a glass rod if necessary. Enough time should be allocated to hold back that the experiment can be make in a calm and refined fashion to avoid any oversights in the time taking. refreshed and clear rulers should be used to beat the bubbles. The molarity of the chemicals should be checked with titration or some other form of effigy checking the molarity.
