    hospitals and at homes. However, hydrogen peroxide is toxic to cells in high levels due to how readily it transforms to a hydroxyl radical, OH- (5). Catalase is an enzyme whose job is to break down hydrogen peroxide, so it does not convert to the hydroxyl radical. When hydrogen peroxide is present in the cell, catalase catalyzes a reaction that transforms hydrogen peroxide into water and oxygen gas. This reaction causes bubbles to form (4). Without catalase, hydrogen peroxide can kill the

    rates of reactions. Several experiments will be conducted using various combinations of concentrations of the reactant (hydrogen peroxide) and a catalyst (potassium iodide), as well as one pairing in which a change in temperature is the only variable. Data collected will be used to determine the rate law, rate constant, and activation energy for each of the reactions Hydrogen peroxide (H_2 O_2) naturally decomposes into water (H_2 O) and oxygen gas (O_(2 )) according to the following balanced equation

    containing more than about 8 percent hydrogen peroxide are corrosive to the skin. First recognized as a chemical compound in 1818, hydrogen peroxide is the simplest member of the class of s. Of the several processes of manufacture, the principal ones involve reactions of oxygen from the air with certain organic compounds, especially anthraquinone or isopropyl alcohol. Major commercial grades are aqueous solutions containing 35, 50, 70, or 90 percent hydrogen peroxide and small amounts of stabilizers

    Hydrogen Peroxide Investigation When hydrogen peroxide is added to a piece of fresh potato, bubbles of gas are seen to form. When a bigger piece of potato is used, a larger number of bubbles is produced. A possible explanation for this observation could be that oxygen is produced when hydrogen peroxide is broken down by the enzyme catalase. A large piece of potato will contain a higher amount of catalase than a smaller piece and therefore produces a greater volume of oxygen. The Task

    Decomposition of Hydrogen Peroxide Aim: My aim in this experiment is to investigate the effect of changing the concentration of the substance (Hydrogen Peroxide) in an enzyme controlled reaction. Prediction: I predict that the higher the amount of Hydrogen Peroxide I use then the faster the displacement reaction will be. Therefore, the less substrate I use then the slower the displacement reaction will be. Hypothesis: I performed a preliminary experiment to distinguish the amount of

    Comparing the Reaction Rates Between Potato and Hydrogen Peroxide Against Liver and Hydrogen Peroxide Through Loss in Mass Background information: Catalase is an enzyme that is found in all cells. This means that it is an intracellular enzyme. And enzyme is a biological catalyst. A catalyst is some thing that speeds up a reaction without being changed itself. Because of this enzymes and catalysts can be used again and again. Enzymes are protein chains that have a primary, secondary and

    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

    How the concentration of enzymes controls the breakdown of Hydrogen Peroxide? Aim- We are investigating the effect of changing the concentration of the enzyme catalase has on the rate of breaking down of Hydrogen Peroxide. Background Info- This experiment will involve some soft potato. Potato has a very high enzyme count, that¡¦s why we use it in this experiment. This enzyme is called catalase. It is used in our body to break down food and other things that we might digest. A catalase speeds

    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. According to Kate
