Hydrogen peroxide

Hydrogen peroxide or H2O2 could be used for a lot of things and we bet you have a bottle of it in the medicine cabinet or in some drawer. A lot of people don´t know that hydrogen peroxide the only germicidal agent made only of water and oxygen. This is a natural substance that can be found in all living thing and its oxidation potential is used to treat diseases, fight infections and neutralize germs. Hydrogen peroxide can be quite dangerous if it is ingested, and depending on its concentration

Hypothesis Hydrogen peroxide sometimes can be utilized to produce oxygen gas. One of the way to cause the decomposition reaction is to add some catalyst. Liver solution contains catalase which is from the liver cells. After the cells being broken down, the catalase is released and dissolves in water. As the catalyst, liver solution can cause the reaction of hydrogen peroxide and therefore release the oxygen that is produced in the reaction. If the volume of hydrogen peroxide increases while other

of this study was to test the rate of reactivity of the enzyme catalase on hydrogen peroxide while subject to different concentrations of an inhibitor. The hypothesis was that hydrogen peroxide will be broken down by catalase into hydrogen and oxygen, where a higher concentration of inhibitor will yield less oxygen, resultant of a lower rate of reaction. Crushed potato samples of equal weight were placed in hydrogen peroxide solutions of various temperatures. The results showed that less gas was produced

Abstract: The percent of hydrogen peroxide was calculated. Hydrogen peroxide was decomposed under various conditions with a catalyzed with the mass, volume and temperature written down. The results were 2.82% of hydrogen peroxide was in the aqueous solution. Introduction: The purpose of the Hydrogen Peroxide Lab is to determine the percent hydrogen peroxide- by knowing the number of moles of oxygen gas produced- in an aqueous solution- this is done by decomposing hydrogen peroxide under various conditions

affecting the catalytic decomposition of Hydrogen peroxide Please refer to the additional files for tables/graphs. Aim- The purpose of this investigation is to investigate how certain factors affect the catalytic decomposition of Hydrogen peroxide. I will investigate the effect of altering the mass of catalyst used on the rate of the decomposition of Hydrogen peroxide. Introduction- The decomposition of Hydrogen peroxide is a process by which Hydrogen peroxide decomposes into water and Oxygen. It

Hydrogen Peroxide Rate of Reaction By Kevin Frappier 10/15/2017 BIOL133 Abstract The reason for conducting this lab is discover is changing hydrogen peroxide (H2O2) concentration will affect the rate of reaction. During the experiment, the H2O2 rate will be changed and pressure will be measured using a gas pressure sensor. The data suggests that as the hydrogen peroxide concentration increases, the rate of diffusion increases and that my hypothesis is valid. Introduction Hydrogen peroxide

Effect of the concentration of hydrogen peroxide on volume of oxygen gas production, when reacted with catalase. Abstract The aim of this laboratory experiment was to investigate the effect of hydrogen peroxide concentration on the rate at which oxygen is produced when the volume and temperature of 50% catalase and volume of hydrogen peroxide solution are kept constant. It was expected that if the concentration of hydrogen peroxide increased, then the production rate of oxygen gas would also increase

and Evaluation: The purpose of this lab was to explore how certain quantities of hydrogen peroxide would affect the amount of oxygen gas produced in the following lab. The hypothesis of the lab in question was that, if the amount of Hydrogen peroxide added to the catalase (liver) solution increased, then the amount of oxygen gas produced would be much greater. This is because the greater amount of hydrogen peroxide in a catalase solution will result in there being more solution to deform into oxygen

Enzyme Lab Report Hydrogen peroxide is a toxic byproduct of cellular functions. To maintain hydrogen peroxide levels the catalase enzyme deconstructs hydrogen peroxide and reconstructs the reactants into oxygen gas and water. The catalase enzyme is found inside cells of most plants and animals. Regulating the levels of hydrogen peroxide is crucial in homeostasis and analyzing it’s optimal conditions for performance is just as important. To understand the optimal environment for this enzyme, they

The Effect Of Activated Yeast on Hydrogen Peroxide Kashish Pandey Lekha Pillarisetti, Ruth Rauca, Jason Tran Period 1; 21 October 2015 Abstract The topic of this lab is on biochemistry.This experiment was conducted to show how cells prevent the build of hydrogen peroxide in tissues. My group consisted of Lekha, Ruth, and Jason. There were used two different concentrations of hydrogen peroxide through this experiment , 1.5% and 3%. By testing two different types it is easier to understand
