    Investigation to Identify the Formula of Hydrated Copper Sulphate Aim: I plan to investigate the formula of Hydrated Copper Sulphate and, more importantly, what x stands for in the formula (CuSO4.xH2O). This will tell me how many molecules of water surround each molecule of Copper Sulphate. To do this I plan to work out the amount of water a set mass of Hydrated Copper Sulphate loses when it becomes anhydrous. I will work this out by measuring the difference in mass between the two states

    Before any chemical reactions occurred, there was 0.46 grams of elemental copper metal. After the copper was added to the 250 milliliter beaker containing the 5.0 milliliters of nitric acid, nitrogen dioxide gas came out. The gas color was a light brown color, and the clear nitric acid within the beaker became a green-brown color. Once the chemical reaction concluded and nitrogen dioxide gas stopped releasing from the beaker, 20 milliliters of distilled water was added to the solution, and the color

    Purpose and background The purpose of this lab is to determine the mass of anhydrous salt and H2O in a hydrate solution to calculate the empirical formula of the hydrate. To make this determination, the H2O in the hydrate is driven off to calculate the mass of the water and anhydrate. By driving off the H2O, the anhydrate will be left behind in the evaporating dish and may even change color or texture. The H2O in the hydrate is run off through the process of evaporation, where a liquid is heated

    Objective: To observe the single replacement reaction between iron and copper(II) sulfate, calculate the mole ratio and find percent error. Theory: Mole relations: One mole (abbreviated mol) is equal to 6.02×10 23 molecular entities (Avogadro's number). Each element has a different molar mass depending on the weight of 6.02×10 23 of its atoms (1 mole). The total number of atoms of each element must be

    Evaluation of the Fractal Dimension of a Crystal Abstract The purpose of this experiment was to determine the effects of voltage and molarity changes on the fractal dimension of a Cu crystal formed by the re-dox reaction between Cu and CuSO4. Using the introductory information obtained from research, the fractal geometry of the Cu crystals was determined for each set of parameters. Through the analysis of data, it was determined that the fractal dimension is directly related to the voltage

    Error Analysis The percent error or percent yield between the theoretical yield of Cu produced and experimental value of Cu produced was approximately 107 %. One source of error, which was a scientific error, was that leaving the Cu precipitate in the cupboard for week allows dust to accumulate on the sample. When dust accumulates on the Cu precipitate for a period of one week, it adds additional mass when weighed. This is because dust has mass, and as more and more dust accumulate, the accumulation
