Concentration of Acetic Acid in Vinegar Nalebra Barnett, AAHCA, BSHA University of Central Oklahoma General Chemistry II Lab March 28, 2017 Dr. Lane Whitesell Lab 12. Concentration of Acetic Acid in Vinegar. This laboratory is to determine the concentration of acetic acid in vinegar using molarity and percent by mass of acetic acid in vinegar. This means, vinegar is a crucial solution of acetic acid (HC2H302) in water. Molarity (in mole/L), or mass percent expressed 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 sodium…

The objective of this experiment is achieved as the molarity of the solution and the percent by mass of acetic acid in vinegar have been determined by using titration with a standardized sodium hydroxide solution. In order to standardize the sodium hydroxide solution or based solution, titration of solution with a primary standard acid solution has been done. Sodium hydroxide, NaOH is used as the base meanwhile potassium hydrogen phthalate, KHP is used as primary standard acid. The first…

The procedure of the experiment includes two parts: 1. Determination of the Freezing Point of Glacial Acetic Acid: to record the temperature of acetic acid every 30 seconds until it reach 300 seconds (5 minutes). 2. Determination of the Molar Mass of an Unknown Compound: to record the temperature of the mixture between unknown solid and glacial acetic acid. After that, put the ice-water mixture into the tube and record the temperature every 30 seconds. Pre lab questions: 1. Solute: dissolved…

ABSTRACT Objective: The purpose of the study is to compare and evaluation of the diagnostic efficiency of Toluidine Blue, Lugol’s iodine and Acetic acid in the detection of potentially malignant disorders (PMD’S). Materials and methods: The study population consisted of 30 patients with clinically suspicious PMD’S. The lesions were stained consecutively with toluidine blue, lugol’s iodine & acetic acid depending on the retention of the dyes, the biopsy site was determined and sent for…

In experiment 10, we diluted solution of sodium hydroxide, NaOH to determine the molar concentration of acetic acid which was present in the vinegar brand Shaw’s. We measured out small volumes of the brand Shaw’s vinegar and used a buret to figure out what was the volume of the sodium hydroxide that was required to neutralize the vinegar. Titration is a process that slowly adding one solution to another until the reaction between the two solution complete. The reaction we used during the…

Results Unit 800 produces ethylene and acetic acid through the partial oxidation of ethane. Ethylene, the most abundant product from the unit, is partitioned such that half of the product is used as a feed source for Unit 600 and the other half is sold on the market. Ethylene purity must reach at least 99.5% to be sold as reagent grade. The second desired product, acetic acid, is also sold on the market, at 99% purity. Unit 800 consists of a fired heater to preheat the reactants, an…

This objective was accomplished when the researchers synthesized esters of raspberry, banana and peach through reacting indicated alcohols and carboxylic acids in the presence of an acid catalyst in a round bottom flask and reflux condenser. This enabled the researchers to synthesize the following esters: pentan-2-yl acetate, benzyl acetate, butan-2-yl methanoate. The researchers, however, were unable to purify the said crude product due to the instructions given to them by their…

The objective of this experiment is to prepare isopentyl acetate by direct esterification of acetic acid and isopentyl alcohol. Esterification is carried out by utilizing organic chemistry techniques, such as heating under reflux, extraction, and simple distillation. The acid and alcohol would be combined and heated under reflux; which heats/speeds up the reaction without having the reactants/products evaporate or explode. During reflux, the heating and condensing of the vapor prevents any loss…
