    Determination of a Rate Law Megan Gilleland 10.11.2012 Dr. Charles J. Horn Abstract: This two part experiment is designed to determine the rate law of the following reaction‚ 2I-(aq) + H2O2(aq) + 2H+I2(aq) + 2H2O(L)‚ and to then determine if a change in temperature has an effect on that rate of this reaction. It was found that the reaction rate=k[I-]^1[H2O2+]^1‚ and the experimental activation energy is 60.62 KJ/mol. Introduction The rate of a chemical reaction often

    INVESTIGATION #2 DETERMINATION OF THE WATER OF CRYSTALLISATION April 4‚ 2012 OBJECTIVE: Chemical compounds that contain discrete water molecules as part of their crystalline structure are called hydrates. Hydrates occur quite commonly among chemical substances‚ especially among ionic substances. More often than not‚ such compounds are either prepared in‚ or are recrystallized from‚ aqueous solutions. Hydrates exist for ionic compounds most commonly‚ but hydrates of polar and non polar covalent molecules

    Determination of Water in a Hydrate DESIGN – Aspect 1: Defining the problem & selecting variables Research Question: What percentage of Copper Sulfate Hydrate is water? Background Information: There are many ionic compounds that contain one or more waters of hydration in their formulae. They exists either in anhydrous or hydrated form. Most anhydrous compounds have a strong tendency to absorb water from the humidity in the atmosphere and shifts into a hydrated form. Because of

    Bohnenberger Professor Van Doorn ENVS 150-002 2 March 2015 Water Quality Lab Report Introduction: When people are asked about how water is characterized‚ they usually will think of saltwater‚ freshwater‚ safe-to-drink freshwater‚ and tap water. Only a few people understand that water and its quality are characterized in several other ways beyond salt‚ fresh‚ and tap water. In 1967‚ the Water Quality Act‚ which was an amendment of the Federal Water Pollution Control Act‚ was passed. The Act required

    Neutralization Titrations: The Determination of Sodium Carbonate from Unknown Soda Ash Unknown # I. Purpose: The goal of this experiment is to determine the weight % of Na2CO3 through the preparation of NaOH and HCl standards. The molarity of the standards will be found through titration of KHP for NaOH‚ HCl vs the known NaOH‚ and the unknown Soda Ash sample vs the known HCl. II. Equations and Sample Calculations: Titration of HCl with NaOH: Complete Equation: HCl (aq) + NaOH (aq) 

    The intention of the “Foul Waterlab was to purify a sample of sewage water and conserve as much as possible. The water should be clean enough to wash your hands with. My hypothesis is that the water will be cleaner than the initial water sample‚ but not to the standard that I would wash my hands with. Significant terms to know include purification‚ filtration‚ adsorption‚ volume‚ clarity‚ dissolved‚ filtrate‚ impurities‚ pipette‚ clay triangle‚ funnel cone‚ iron ring‚ beaker‚ and Erlenmeyer flask

    Kaileah Diaz November 10‚2017 Period: 3 Weathering Lab Report Water erosion is usually caused by rainfall and runoff on a slope‚ and the magnitude of water erosion depends on the type of soil. This can occur on river banks‚ seashores‚ streams‚ or even seaside cliffs. Muddy water is also a sign of erosion. There are brown hue results from the suspension of rock and soil particles inside the water. Water erosion usually happens in the springtime because there is usually a lot more rainfall and

    Steel Wool Scissors Ruler Lemon Juice Orange Juice Vinegar Distilled Water Four Small Bowls Thin Towel Tall plastic cup Graph Paper Procedure: Before beginning your experiment‚ make sure that the distilled water has been opened and exposed to the air for at least a few hours. This will allow it to absorb some carbon dioxide from the atmosphere and lower its pH from a level of about 7 to about 5.8. The distilled water will act as a model for "normal" rainwater‚ which has a pH of about
