Indirect determination of ∆H via Hess’s law Conclusion & Evaluation Research question: What is the ∆H/mol of hydration of CuSO4 (anh)? The ∆H/mol of hydration of CuSO4 (anh) is -70.2‚ according to the experiment done in class. It was determined by applying the Hess’s law‚ using two reactions 1) CuSO4-5H2O ----> CuSO4 (aq) + 5H2O 2) CuSO4 (anh) -----> CuSO4 (aq) According to the Hess’s Law‚ which states that the total enthalpy change for a chemical reaction is the same disregarding

Formaldehyde is known to be one of the most reactive organic compounds. It can be produced by various reactions. It can produced by methods such as: Methanol undergoes an oxidation reaction in the presence of catalysts‚ ethyl-alcohol‚ coal gas‚ ethylene‚ methane‚ glycol‚ glycerin‚ and carbon monoxide Production of formalin form methanol: Formaldehyde is manufactured from methanol and air either by using a silver catalyst or a metal oxide catalyst. Using Silver Catalyst: To convert methanol to

Data Collecting and Processing Raw data Table of raw data Qualitative observation: At the start of the experiment‚ the crystals were blue. During the heating‚ the crystals turned white which means that they lost their water molecules. The source of hydrated copper sulphate consists of both small grains and large grains of the salt. Therefore during the heating process‚ the smaller grains of the hydrated salt turned from blue to white in just 1 minute. In other words‚ there is an uneven heat

Purpose: The purpose of this experiment is to: determine the limiting reactant of a chemical reaction that involves iron filings and a copper sulfate solution. Second‚ to determine the mole ratios between iron and copper and to show that a single replacement reaction occurs when iron and copper sulfate react with each other. And lastly‚ to determine/calculate the percent yield to better analyze the chemical reaction between iron and copper sulfate to produce copper and iron sulfate. The method

Note: I couldn’t paste in pictures and diagrams so please excuse any large spaces. Planing my investigation Method 1.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

When you mix copper‚ silver‚ and nitrate together‚ you will end up with silver nitrate solution will turn blue (it has become copper nitrate). On the piece of copper‚ there would be a coating of solid silver. If a chemical reaction is going to be observed when chemicals are mixed‚ heated or any other means of altering the substance‚ then we will be able to predict the products formed. If it is observed that in the original versus the changed substance no new substances are formed‚ the change is reversible
