    Melissa Carrithers AP Chemistry period 6 2-11-15 Determination of Ka of Weak Acids Purpose: The purpose of this lab is to find the strength of weak acids by determining the equilibrium constants for their ionization reactions in water. Is to use their measured pH values to calculate the pKa for the two unknown weak acids thus determining their identities. Hypothesis: If we neutralize a solution that contains a weak acid by adding a strong base to the solution‚ then the ions will be isolated and

    Weak Acid Titration Abstract: Our method for determining the unknown weak acid was to determine the equilibrium constant K from the molecular weight of the weak acid from our titration data. In this lab the acid Potassium hydrogen phthalate and two unknown acids were titrated. We determined the molar mass of the Potassium hydrogen phthalate‚ for the unknown acids we calculated the molar mass and the Ka values. We used NaOH as the known base for titrating in all three of the titrations. Our

    April Goodson CHEM 242L-002 February 20‚ 2013 Oxidation of Cyclohexanone to Adipic Acid Abstract The cyclic ketone cyclohexanone was oxidized to adipic acid using the oxidizing agent nitric acid. The experiment yielded 0.2667 grams of adipic acid‚ giving a percent yield of 113.97%. Although the product was allowed to dry for one week‚ residual moisture was still present in the sample and a melting point could not be obtained. This error in the experiment either resulted from adding too much

    What Causes Acid Rain? {2} {2} Acid rain caused by a chemical reaction that begins when compounds like sulfur dioxide and nitrogen oxides are released into air. These substances can rise very high into the atmosphere‚ where they mix and react with water‚ oxygen‚ and other chemicals to form more acidic pollutants‚ known as acid rain.{2} Sulfur dioxide and nitrogen oxides dissolve very easily in water and can be carried very far by wind. As a result‚ the two compounds can travel long distances where
