Report (Redox Reactions) Questions: • What will happen when you put zinc in copper II sulfate? • What will happen when you put copper in copper II sulfate? Predictions: • We can predict that zinc will react with the aqueous solution of copper II sulfate and we will notice a reaction. We can also predict that the copper will not react with the solution of copper II sulfate and no reaction will be noticed. Hypothesis: • It is hypothesized the zinc metal will have a precipitation reaction with the solution

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

Firstly I will measure 20ml of Copper Sulphate solution (CuSO4) in a measuring cylinder‚ for precise accuracy‚ and then pour the solution into test tube. I will place the test tube into a beaker and insulate the test tube‚ for minimum heat loss. (As shown in the diagram above.) 2.Secondly I will measure the required amount of Zinc (Zn) on a weighing scale‚ again for precise accuracy. I will then measure the starting temperature using a thermometer. Next I will pour the Zinc into the test tube containing

Internal Assessment 2011 Candy Au Introduction The reaction between zinc and copper (II) sulphate is endothermic. If an excess of zinc powder is added to a measured amount of aqueous copper (II) sulphate in a calorimeter and the temperature change is recorded over a period of time‚ the enthalpy change of the reaction can be experimentally determined. Assumption 1. Mass of H2O in 100cm3 of CuSO4 solution is 100g 2. Specific heat of solution is 4.18 kJ kg-1 K-1 which is the same as the specific

Determining the Percent Copper and Zinc in Pennies from Density Lab Report Procedure: For pre-1982 pennies- Mass 10 pennies‚ record data. Fill a 100mL graduated cylinder to 40mL or enough to fully submerge the pennies with water‚ record the volume in data table. Carefully place the pennies into the graduated cylinder‚ record the final volume of the water in data table. To find the volume of the pennies‚ subtract the final volume from the initial‚ record the data. Repeat this procedure twice more
