In this lab experiment, around 5 grams of hydrogen peroxide went through a chemical reaction with potassium iodide, producing oxygen gas and water vapor. After three trials of the experiment concluded, Dalton’s law of partial pressure and the ideal gas law was used to determine the number of moles of oxygen produced and the percent hydrogen peroxide in an aqueous solution. The average number of moles of oxygen produced within the experiment was 0.002537 mol. O2 and the average mass percent of hydrogen peroxide was calculated as 3.434%. The mass percent of hydrogen peroxide was slightly over the accepted amount of 3%, indicating that some tiny errors had occurred during the experiment. The purpose of this experiment was to illustrate Dalton’s

    Living organisms undergo chemical reactions with the help of unique proteins known as enzymes. Enzymes significantly assist in these processes by accelerating the rate of reaction in order to maintain life in the organism. Without enzymes, an organism would not be able to survive as long, because its chemical reactions would be too slow to prolong life. The properties and functions of enzymes during chemical reactions can help analyze the activity of the specific enzyme catalase, which can be found in bovine liver and yeast. Our hypothesis regarding enzyme activity is that the aspects of biology and environmental factors contribute to the different enzyme activities between bovine liver and yeast.

    The Effect of a Catalase on the Breakdown of Hydrogen Peroxide Aim To follow the progress of a catalysed reaction by measuring the volume of gas produced as the reaction proceeds. Using the initial rates of a series of experiments I will be able to find the orders of the reaction with respect to enzyme and substrate. Also to find out if concentration has an effect on the reaction when an enzyme is used to accelerate the breakdown of hydrogen peroxide.

    The purpose of the experiment conducted is to understand the role of enzymes in maintaining life and to be able to identify and explain various factors that affect enzyme functions. Make sure to be wearing lab appropriate clothing, a lab coat, and safety goggles at all times since this experiment involves you handling dangerous chemicals like hydroxylamine. For this experiment one of the main materials needed is a spectrophotometer. The use of the spectrophotometer is very important in this experiment. You will test three concentrations of enzyme (0.5 ml, 1.0 ml, and 2.0 ml of turnip extract) and three concentrations of substrate (0.1 ml, 0.2 ml, and 0.4 ml hydrogen peroxide). You always need to make sure you have a control, the control in this experiment is the turnip extract and the color reagent guaiacol. Increasing the temperature increases the rate of an enzyme reaction, decreasing the temperature decreases the rate of an enzyme reaction. Denaturation is a process in which proteins or nucleic acids lose the quaternary structure, tertiary structure and secondary structure. Hydroxylamine is a colorless inorganic compound and an odorless white crystalline solid.

  • Protein Synthesis Lab Report

    The paper, Function of Aggregated Reticulocyte Ribosomes in Protein Synthesis by A. Gierer, details the findings about a study to answer the question whether multiple ribosomes can operate on one molecule of messenger RNA simultaneously. Firstly, background information is necessary for understanding this paper. Ribosomes, the organelle where protein synthesis occurs, require a messenger RNA to be attached to it to be labelled active. Active ribosomes have an increased molecular weight due to the mRNA which in turn causes a higher sedimentation coefficient. The value of the sedimentation coefficient is calculated by timing the movement of a particle in a medium of known viscosity.

    Once the test tubes were in place to insert hydrogen peroxide the changes were observed. The raw liver produced large amounts of bubbles which are made up of oxygen, in contrast to this results the cooked liver produced a minor amount of oxygen bubbles due to the fact that enzymes were denatured once it was boiled. The raw potato produced a considerate amount of oxygen bubbles illustrating that the enzymes within it were in proper shape, however, the cooked potato produced the least amount of bubbles in the entire experiment demonstrating that a change in temperature denatures an enzyme causing it to malfunction and become unable to break apart a hydrogen peroxide molecule. In conclusion, the results of this experiment proves the fact that

  • Enhancing Plant Growth with Hydrogen Peroxide

    895 Words  | 2 Pages

    Hydrogen peroxide (H2O2), according to Bryce Fredrickson (1999-2014), has many useful properties due to its extra oxygen atom. Hydrogen peroxide consists of two hydrogen atoms and two oxygen atoms, whereas water (H2O) consists of two hydrogen atoms and only one oxygen atom (Balcony Garden Web, 2016). Hydrogen peroxide has many uses including cleaning, bleaching, and a few health benefits (Fredrickson, 1999-2014), however the main focus of this research project is on plant growth.

Using a graduated cylinder, measure 25 mL of the bleach into the beaker very precisely and pour it into a small Styrofoam cup. To help stabilize the cup, rest it inside of a beaker. Next, measure out 25 mL of the thiosulfate solution in a different or clean graduated cylinder.

  • Enzyme Catalyzed Reaction Lab Report

    514 Words  | 2 Pages

    In this lab, it was determined how the rate of an enzyme-catalyzed reaction is affected by physical factors such as enzyme concentration, temperature, and substrate concentration affect. The question of what factors influence enzyme activity can be answered by the results of peroxidase activity and its relation to temperature and whether or not hydroxylamine causes a reaction change with enzyme activity. An enzyme is a protein produced by a living organism that serves as a biological catalyst. A catalyst is a substance that speeds up the rate of a chemical reaction and does so by lowering the activation energy of a reaction. With that energy reactants are brought together so that products can be formed.

    My hypothesis was I think that if we change the temperature of the enzyme it will have an area where the enzyme works very well, but if we increase or decrease the temperature too much, it will slow the productivity. If we change the pH of the enzyme, there will be an area where it is extremely productive, but if it gets too acidic or basic the productivity will slow. If we change the concentration by increasing the amount of enzymes, it will be more productive. T think this because your are having more than 1 enzyme work on one task. I you decrease the amount of enzymes, the productivity will be slower because there are less enzymes working on that certain task. The data refutes my hypothesis because I found that the enzymes work best in one

    The first experiments investigate the order of reaction with respect to the reactants; hydrogen peroxide, potassium iodide and sulphuric acid by varying the concentrations and plotting them against 1/time. An initial rate technique is used in this experiment so ‘the rate of reaction is inversely proportional to time.’ To find the order of reaction in respect to the reactants, 1/time is plotted against the concentration of Hydrogen Peroxide using the equation:

    I picked the science experiment elephant toothpaste this year, because it seems interesting and fun. It is also a way to test if the removal of oxygen in these experiments will actually work. I have four different experiments. Two out of the four experiments I am testing, is to see if there is a different reaction time and size between yeast and potassium permanganate and the percentage of the hydrogen peroxide. My third and fourth are tests of elephant toothpaste is to see if adding cornstarch has a color reaction to the potassium iodide to make it look like it is “glowing”, or if the yeast and fluorescent dye will make it look “glowing”. I think the elephant toothpaste that uses 50% hydrogen peroxide and potassium permanganate will have the

    An Investigation into the Decomposition of Hydrogen Peroxide Aim: To investigate the rate of decomposition of H2O2 with different amounts of catalyst (MnO2). Hypothesis: When H2O2 and a catalyst are mixed together, the catalyst would break down H2O2 into water and oxygen. This will result in bubbles being produced. With the data of these oxygen bubbles, the rate at which H2O2 decomposed could be found out. 2H2O2 (l) à2H2O + O2 The controlwould be to maintain the same temperature (room temperature) and to use the same amount of hydrogen peroxide (10ml) in all the tubes.
