    Danika Ng CHEM 1252 L Exp 12: Thermodynamic Analysis of Chemical Equilibria INTRODUCTION The reaction being done with borax and HCl is an acid base reaction. The K constant expression of the reaction is Kc = [Na^+][B4O7^-2]. A titration is needed for this experiment because when a strong acid with a known concentration is added to a weak base, the unknown concentration of the weak base can be found, which can then find the moles of the weak base, which can then find the Kc. The first law of…

    • 5 Pages

    CHAPTER 1 INTRODUCTION 1.1. Introduction Caprolactam (CPL) is an organic compound with the formula (CH2)5C(O)NH. This colourless solid is a lactam or a cyclic amide of caproic acid. Caprolactam was first described in the late 1800s by Gabriel and Mass, when it was prepared by the cyclization of ε-aminocaproic acid, the product of the hydrolysis of caprolactam. In the months after Schlack’s discovery the first stocking were produced from Perlon. All the Perlon produced went to the war effort.…

    reaction with vinegar? Aim: To find out how different amounts of baking soda (soda bicarbonate) affect the length of its chemical reaction with vinegar (acetic acid). Hypothesis: If the amount of baking soda is increased then the length of its reaction with vinegar will increase because there will be more soda bicarbonate for the acetic acid to react with. Equipment:  Baking Soda  Vinegar  5 glasses  Safety glasses  Measuring Spoons  Stopwatch  Scale Variables: -Independent variable:…

    • 9 Pages

    Introduction Experiment five was a two-part experiment meant to have us practice our skills and then use those skills in actual data collection and analysis. In part one we used a sample of sodium saccharinate combined with a sample of a metal halide salt, our group used copper(II) chloride. The combination of these two samples allowed for the synthesis of a metal complex. In part two of the experiment we used a procedure similar to part one in order to collect phosphorus out of a sample of…

    Acid Rain Effects

    • 1199 Words
    • 5 Pages

    Acid rain is a rain that is more acidic (has more hydrogen ions) compared to normal rain and it has serious negative effects to nature and people. It is a mixture of wet and dry depositon that contain high amounts of nitric and sulfuric acids (see Figure 1). These gases come from electric generation, factories, forest fires, burning fossil fuels and acid rain forms when these gases react with water, oxygen and air. Wet deposition happens when acid chemicals fall to the ground in a rain or snow…

    Lab Experiment

    Conclusion: The general conclusion that I was able to produce about the effects of salt on the boiling point temperature of water is that with the addition of salt, the boiling point temperature of water increases. The results of the lab experiment do agree with my predictions and I can accept my initial hypothesis. However, I believe the data would be more consistent and solid had 2M and 4M of NaCl had been included in the experiment, rather than jumping from 1M to 3M to 5M. Discussion: For…
