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

The reaction order‚ based on the rate law‚ was first order with respect to crystal violet and second order with respect to OH-. The rate law was as follows: Rate law = k [CV]1[OH-]1 where k equaled 2.61. In order to determine the reaction order with respect to crystal violet‚ the graph that described the relationship between ln[CV] and time (seconds) was Figure 2. Not only did Figure 2 generate a more linear relationship‚ but it had the highest R2 value of 0.992 than ([CV] versus time) and ([1/CV]

(Starch) when adding the three drops of Iodine to each tube observe the color change. When performing this test the chemical with the larger amount of iodine will be identified. The larger the amount of iodine in the chemical will result in a purple/black color. The iodine/starch complex has energy level spacings that are just for absorbing visible light-giving the complex its intense purple/black color. The method to be used‚ consist of three drops of iodine in the chemical filled tube that is to

this experiment was to use Iodine‚ Benedict and Biuret to test the reaction of the following 12 samples: 1% glucose‚ 0.3% glucose-1-phosphate‚ 1% maltose‚ honey‚ 1% sucrose‚ 1%lactose‚ 1% glycogen‚ 1% starch‚ protein‚ beer‚ distilled water and an unknown solution (test tube: 300). The iodine test for starch was to test how would starch reacted if we put iodine in it. The color of starch before the test was clear. The color of the iodine was brown. When you added iodine into starch‚ the result was

Effect of Iodine on mercury concentrations in dental-unit wastewater John Michael Panganiban and Ian Jasper Ocampo Objective: This study was undertaken to determine whether iodine used to control bacteria in dental unit wastewater could increase mercury concentrations in dental wastewater. Introduction: Two of the major concerns in dentistry are biofilm in dental unit waterlines and the contamination of dental unit wastewater with mercury. Biofilms are microscopic communities that consist

To determine the rate equation for the reaction between Hydrogen peroxide and iodide ions‚ and to investigate the effects of a catalyst and temperatures on the reaction and to derive the activation enthalpy. Background knowledge: 1Hydrogen peroxide reacts with iodide ions producing iodine‚ when in an aqueous acid solution. H2O2 (aq) + 2I- (aq) + 2H3O+(aq) I2 (aq) + 2H2O(l) To detect iodine you can look at the color shown by the addition of starch solution. Iodine also reacts with sodium
