Analyzing a Hydrogen Peroxide Solution Purpose: The technological purpose of this investigation is to test and evaluate the percent concentration of consumer solution of hydrogen peroxide. Problem: What is the percent concentration of hydrogen peroxide in a consumer product? Design: An acidic solution of primary standard‚ iron (II) ammonium sulfate-water (1/6)‚ is prepared and the potassium permanganate standard. A 25.0 mL sample of a consumer solution of hydrogen peroxide is diluted to 1

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

Experiment 8: Hydrogen Phosphate Buffer Systems Purpose The purpose of the lab was to create a buffer solution and observe the capacity of the phosphate buffer system. Also‚ the experiment was meant to provide experience with the calculations and mathematics involved in creating the buffer solution. Finally‚ the lab was designed to provide an insight and appreciation for the necessity and complexity of buffers in our physiology and in the environment. Procedure No deviations were made from

of a component causes the equilibrium to shift to the side from which the component was removed. D. Is this reaction endothermic or exothermic? How do you know? When acid is added to water the reaction is strongly exothermic. Because the hydrogen ion is so tiny‚ a large amount of charge is concentrated in a very small

throughout the whole experiment. We will wear goggles and an apron or lab coat to protect our eyes and clothes. As we are using enzymes and Hydrogen Peroxide we need to be extra careful‚ ensuring they don’t come into contact with our eyes‚ skin or clothes. Catalyse is an enzyme found in all living cells. It makes Hydrogen Peroxide decompose into water and Oxygen. We will be measuring the amount of Oxygen released from the Hydrogen Peroxide. In order to do this we will use a measuring cylinder

PART A It is hypothesised the strongest method for curing eye defect is Gas permeable contact lenses (GP lenses). These lenses are able to maintain their shape instead of adapting to the shape of the cornea due to its firm oxygen permeable material. The lenses can provide improved vision‚ deposit resistance and are inexpensive as they are long lasting. PART B Myopia and Hyperopia are both conditions caused by refractive errors in the eye and possess an array of symptoms PART C Vision is able to
