Hydrogen Peroxide Lab Report

The Use of Catalysts in Degradation

Introduction

Hydrogen peroxide, the same mild acid that many people use to disinfectant their kitchens or treat cuts and abrasions, is also produced by the body to keep cells healthy (sciencedaily.com). For example, when there are bacteria in the body more hydrogen peroxide is produced by some cells to fight the infection. However, hydrogen peroxide is a potent oxidizing agent and if too much is produced damage to the cells and some proteins can occur. Cells in the human body have an enzyme called Catalase that breaks down hydrogen peroxide into water and oxygen, in turn, preventing cellular damage. Hydrogen bonds create enzymes by the different patterns of hydrogen bonds between amino acid components. The purpose of experiment 1 was to measure the bubbles as an indirect measure of degradation. A well-developed hypothesis would be the more

The test tubes were numbered with a marker and were numbered 1A, 2A, 3A, and 4A. Next number four test tubes as 1B, 2B, 3B, and 4B and place 1 droplet of H2O2 in each of the test tubes. Next, the test tubes were placed in the designated temperatures for 5 minutes. Determine the temperature of each test tube using a Celsius thermometer; be sure to document the readings. Tubes 1A and1B were placed in a beaker of crushed ice, Tubes 2A and 2B were placed in test tube racks at room temperature, Tubes 3A and 3B were placed in a beaker of water at 70 degrees Celsius, and Tubes 4A and 4B were placed in boiling water. After 5 minutes tubes 1B, 2B, 3B, 4B containing the hydrogen peroxide needs to be poured into the reciprocal test tubes marked 1A, 2A, 3A, and 4A. Lastly, after 1 minute using a metric ruler measure and document the thickness of the foam layer for each test tube. Be sure to wash all glassware and other equipment and drain the excess
