    I then added 50 ml of distilled to the test tubes A1, B1, C1 and D1, then titrated them with the potassium permanganate solution (making sure to add 15 ml 3M sulfuric acid in each), then recorded the amount it took for them to turn pink. Data A. Standardization of KMnO4 solution: Sample g Na2C2O4 moles Na2C2O4 (x 10^-3) moles KMnO4 (x 10^-3) ml KMnO4

    must be performed without adding catalase (enzyme) to the reaction mixture. 1. Accumulate 10 mL of 1.5% hydrogen peroxide (H2O2), two 50-mL glass beakers, 10 ml of 1M sulfuric acid (H2SO4), approximately 6 mL of 2% potassium permanganate (KMnO4) 1 mL of water (H2O), two appropriately labeled syringes (for contamination prevention), white paper, a pipette, aprons, goggles, and gloves. 2. Put on aprons, protective goggles, and latex gloves

    understanding of the relationships between results present by the spectrophotometer. Food coloring was the subject of our first tests with the Spec 20 and our group choose the colors red and blue. Along with the food coloring we would also be running Potassium Permanganate through the machine. By sending light beams of different wavelengths through the solutions we were able to find the absorbance of each solution shown in Table 1 as well as the relationship

  • A Sample Of P Acetamidobenzoic Acid

    The objective of this procedure is to produce a sample of p-acetamidobenzoic acid from the oxidation of p-acetotoluidide with potassium permanganate. Procedure Part A- Preparation of p-Acetamidobenzoic Acid • In a 250 mL Erlenmeyer Flask, 5 g (0.02 mol) of magnesium sulfate crystals were mixed with 1.9 g (0.013 mol) of p-acetotoluidide in 125 mL of de-ionized water. The resulting solution was placed on a hot plate and was steadily boiled until the solution reached 85°C, or until the solution reached

    containing a known concentration of iron (II) ions, (Fe+). The concentration of oxalic acid solution will be determined by titration with the MnO4- solution that had been standardized first. The purpose of this lab is to standardize a solution of potassium permanganate by redox titration with a standard solution of

  • What Is The Importance Of Solubility In Salt Potassium Permanganate?

    806 Words  | 4 Pages

    Purification of a compound is also common practice and is most times done by recrystallization. This is where the solute is dissolved in a solvent at ambient temperature so that pure crystals form when cooled. With the case of an inorganic salt potassium permanganate in an organic solvent, a phase stage reactant is often used. The largest form of experimental error for this experiment was that of approximation, affecting solute-solvent ratios and thus the ability for the solute to dissolve. Since very

    observation. After gathering all the data, we solved for the rate of diffusion of each using the formula. Rate= Final diameter-Initial diameter Time After finishing the Methylene blue experiment, we followed the same procedure to Potassium Permanganate. Each group presented the result to the white board, so that we can compare the results. We kept a record of the results and have a short conversation with our group mates in interpreting the results of the conducted experiment. Towards the
