the more Benedict’s solution (copper sulphate) will be used up. * The precipitate is filtered out then the concentration of the remaining solution can be measured. * This will tell you how much Benedict’s solution has been used up allowing you to estimate the concentration of reducing sugar in the original sample. How Does A Benedict’s Test Work? Benedict’s Solution is a method to determine glucose levels in people suffering from diabetes. It has copper sulphate in it‚ which reacts with

molecules that are in the hydrate. Copper(II) sulfate pentahydrate‚ or CuSO4 * 5H2O‚ is a ratio of one copper sulfate to five (penta) molecules of water. Copper sulfate pentahydrate is a blue hydrate while anhydrous copper sulfate (CuSO4) is white. To get anhydrous copper sulfate‚ copper sulfate pentahydrate must go through an endothermic reaction and have all of its water molecules evaporated. It then becomes the white‚ flaky‚ and chalky material anhydrous copper sulfate. Adding

of zinc with Copper 2 sulfate producing copper and zinc sulfate. How would I solve for delta H? In the second experiment we are trying to determine delta H for the hydration of anhydrous copper 2 sulfate. If anhydrous copper 2 sulfate powder is left in the atmosphere slowly absorbs water vapour giving the hydrate solid. The enthalpy change will need to be determined when 0.025 mol of anhydrous copper sulfate is dissolved in 50mL of water. The enthalpy change of the hydrated copper sulfate when

Copper Sun is a novel by Sharon M. Draper about 15 year old Amari‚ whose village was taken over so she has to cope with the fact that her family is now gone. She also has to deal with the fact that she is being taken away from her true love. Throughout the story Amari displays many emotion‚ two major emotions are loneliness and bravery. Amari becomes very lonely when the fact that her parents and brother are dead becomes a reality. She still has Afi‚ who treats her like her own. On the very rough

The lab in which we conducted last Tuesday was an analysis of a hydrate and what happens to it when it is heated. A hydrate is a crystalline compound which water molecules are chemically bound to it. In the lab‚ we were to analyze the difference in grams of the hydrate and the anhydrate. An anhydrate is the crystalline compound without the water molecules bound to it. During our lab‚ we were to heat up the crucible‚ the crucible with hydrate‚ and the crucible with an anhydrous and write down each

Maria Quin Solubility Lab Purpose: The main purpose of doing this lab is to learn how to interpret solubility graphs and how the temperature does affects the solubility of different substances. There are other objectives of the lab which are learning what are concentrated‚ diluted‚ supersaturated‚ and saturated substances and how can they be identified. The hypothesis of this lab would be that when temperature increases‚ the amount of salt and copper sulfate that can be added in the

LAB REPORT Introduction: In a chemical change‚ the identities of substances change and new substances form. In an equation the substances on the left are the reactants. The substances on the right are the products. In this experiment the objectives are to observe evidence that a chemical change has taken place. Infer from observations that a new substance has been formed. Identify and record observations that show energy is involved in chemical change observe the color‚ solubility of some substances

This lab report will be detailing the steps taken and the results discovered when using spectrophotometry to determine the percentage of copper in a copper-clad penny and the thicknes of the copper layer on the copper-clad penny. After 1982‚ copper coating has been used in the creation of the penny because the cost of pure copper has increase to the point that the amount needed t omake a penny cost far more than the actual value of the penny. This lab allowed us to see just how much copper coating

A hypothesis is often not necessary or appropriate. Enzymes are proteins that speed up chemical reactions in cells. They break down molecules called substrates. Each enzyme has only one substrate that it breaks down. Enzymes are produced in
