upper respiratory tract‚ including most species of Streptococcus and Staphylococcus‚ is to inhibit the growth of aerobic organisms through the presence of oxygen and high concentration of tellurite. Reactive oxygen species compounds such as hydrogen peroxide (H2O2)‚ superoxide anion (O2-) and hydroxyl redical (OH-) are natural byproducts of the normal metabolism of oxygen that can be formed by exposure of cells to free-radical generating molecules like metals and metalloids. ROS compounds are generally

Lab Report #1 Title: Synthesis of Divanillin Abstract: The purpose of this experiment was to synthesize divanillin. This was done via the oxidative dimerization of two equivalents of vanillin‚ using enzyme horseradish peroxidase as the catalyst. Procedure: Lab Handout: Nishimura‚ R.T.; Giammanco‚ C.H.; Vosburg‚ D.A. J. Chem Educ. 2010‚ 87‚ 526-527. Discussion: Mechanism: Reaction 2 Vanillin H2O2 Divanillin 2 H2O

How does it change the pH of strong acids/bases? Why or why not? The addition of water does not have a significant impact on the pH of strong acids and bases‚ but it does have an impact on weak acids and bases. It changes the pH because the hydrogen ions in water increases the concentration in acids and bases. Weak acids and bases have low concentrations of [H+]‚ therefore the addition of water has a large impact on the pH. How does the difference in 1 pH unit change in terms of [H+] concentration

oxidation of hydrogen peroxide to lower activation energy‚ speeding up the reaction. The activity of peroxidase is highly dependent on its environment and most importantly the pH level. Peroxidase has been the focus of many recent studies and is believed to possibly reduce swelling among other things. We conducted an experiment testing the effect different levels of pH had on the reaction rate of peroxidase. In the experiment we created different solutions all containing hydrogen peroxide‚ peroxidase

Chapter I: Introduction A. Background of Study Baking soda was traditionally used as a tooth cleaner before commercial toothpaste became available. Combined with peroxide‚ it makes a potent teeth whitener for much less than expensive whitening toothpastes or strips. Being a naturally occurring compound‚ baking soda is safe for cleaning teeth to a certain extent. It has the property of neutralizing agents that are responsible for causing discoloration and foul

IGSCE Chemistry Notes Oxides Oxides are used to determine whether an element is a metal or a non-metal. Most non-metals are classed as acidic oxides. While most metals are classed as basicoxides. Acidic Oxides * Reacts with water to form acids * Neutralises alkaline solution to form salt + water Basic Oxides * Neutralises acidic solutions to form salt + water Amphoeteric Oxides * These are non-metals which display both acidic and basic properties Alkaline Oxides * Reacts
