  • Baking Soda And Vinegar Lab Report

    its 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…

  • Strong Titration

    solution of acetic acid and sodium acetate was made by combing 15 mL of .5 M acetic acid, 15 mL of deionized water, and 1.020 grams of sodium acetate. A solution of .25 M NaOH was then prepared using 25 mL of .5 Ml NaOH and 25 mL of deionized water. The burette was then conditioned with 10 mL of deionized water twice and twice with 5 mL of .5 M NaOH. The burette was then filled with .25 M NaOH and the initial volume of 25 mL was recorded. A volumetric pipette was then used to add 10 mL of acetic…

  • Acetic Acid Synthesis Lab Report

    the Properties of Acids and Bases Using the Acetic Acid and Sodium Acetate Buffer System Purpose The purpose of this experiment was to explore some of the properties of the acetic acid and sodium acetate buffer system, such as the greatest buffering capacity and the acid and base neutralization ability of several different concentrations of this buffer. Reagents The reagents used were the following: 0.10 M acetic acid, 0.010 M acetic acid, 0.60 M acetic acid, 0.60 M sodium acetate, 0.10 M…

  • Henderson-Hasselbalch Analysis Lab

    the titration curve. In this particular practical acetic acid was titrated with sodium hydroxide. In this reaction the proton (H+ ion) is transferred to the water molecule creating a hydronium ion. Acetic acid is a weak acid, this is because it doesn 't ionise fully when it is dissolved in water. Another way of saying this is the “back” reaction is more successful than the forward one. Below is shown the equation for the dissociation of acetic acid into acetate. The experimental…

  • Buffer Solution Research Paper

    What are buffer solutions? Buffer solutions are solutions in water that mark the mixture of acids and bases. They assist in neutralization response to a certain quantity. Acidic buffer answers are those that have robust acids and weak bases as their components. they're used for neutralizing alkaline solutions. Alkaline or primary buffer answers are those who have sturdy alkalis and weak acids within themixture. they're used for neutralizing acidic aqueous answers. Buffer solutions in the blood…

  • Caprolactam And Nylon 66

    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.…

  • Synthesis Of 6-Deoxycellulose Derivatives Lab Report

    T. Heinze et. al. reported the synthesis of new 6-deoxy-6-pheylethylamino cellulose derivatives with DSamino 0.4-0.6 by nucleophilic displacement of cellulose tosylates (DSTos 0.74 and 1.29) with a racemic mixture of 1-phenylethylamine under homogeneous conditions, in DMF/H2O82, scheme 30. The optical properties of these deoxyamino cellulose derivatives was studied. A regioselective synthesis of 6-amino-6-deoxycellulose, 6-N-sulfonated, and 6-N-carboxymethylated deoxycellulose were…
