Tests for Carboxylic Acid and Derivatives Mary Catherine Sarte‚ John Emmanuel Sy‚ Allurie Umel‚Franklin Yap‚ Mary Christine YouIntroduction Carboxylic acids derivatives are simply groupsof compounds that contain a carbonyl group butwith an electronegative atom attached to thecarbon. The difference in the structure leads to amajor change in reactivity. The reactions of thesegroups of compounds involve nucleophilicsubstitution. Although there are abundant kindsof carboxylic acid derivatives‚ the experimentonly

Acid-Base extraction theory states that when an acid reacts with an organic base it results in a salt that is water-soluble and a neutral molecule that is insoluble. The addition of an acid to a mixture containing acids and bases will result in the acid remaining unchanged and the base reacting to form a salt. The results from the experiment were fairly consistent when separating the strong acid‚ weak acid‚ or the base. In part one of the experiment‚ you had to separate the strong acid. When added

Determination of Ka for a Weak Acid Introduction In the experiment preformed the objective is to titrate a weak acid with a strong base. In a titration of a weak acid with a strong base the titrant is the strong base and the analyte is a weak acid. The reaction that will occur is the direct transfer of protons from the weak acid to the hydroxide ion. The data gathered will be represented on the titration curve‚ a graph of the volume of titrant being the strong base plotted against the pH .The

Premium PH indicator Titration PH
I. Introduction The purpose of this experiment is to determine the pH values of acids‚ bases‚ and buffers of distilled water and 10.0 buffer using measured concentrations of Sodium hydroxide (NaOH) and/or Hydrochloric acid (HCl). Acid is a compound typically having a bitter taste and capable of nullifying alkalis and releases hydrogen ion when added to a solution‚ or containing an atom that can accept a pair of electrons from a base (McKinley‚ Dean O’Loughlin‚ & Stouter Bidle‚ 2016). Bases are water-soluble

Premium Titration Base Erlenmeyer flask
The conventional method was conducted by placing 2.0641 grams of salicylic acid in a dry 125 mL Erlenmeyer flask. In a fume hood‚ 4 mL of acetic anhydride and 5 drops of concentrated sulfuric acid were added to the flask. The contents were swirled in the flask and then heated for 20 minutes in a hot water bath. After the 20 minutes were up‚ 10 mL of cold water were added in 1 mL increments. The flask was cooled for 10 minutes and occasionally stirred. The crystals that formed were collected via filtration

Lay Public (FINAL draft) Benefits of Omega 3 Fatty Acids In the rush to cut calories‚ reduce cholesterol intake‚ and avoid saturated fats‚ many of us have embraced low-fat diets and low-fat foods. But some fats are necessary and "essential" for health. These fats show great promise for fighting the onslaught of heart disease and diabetes‚ possibly even cancer. What are these "good" fats—and how do we get enough of them? The benefits of Omega 3 fats have been researched for quite some time and

is not in the normal blood pH‚ the person can fall sick and it might be harm to the person. The maintenance of blood pH is called acid-base homeostasis. Acid-base homeostasis is a complex synergy that involving lungs‚ kidneys and a buffer chemical in blood and blood cells. BACKGROUND A substance that has high concentration of hydrogen ion in solution is called acid and solution that has low concentration of hydrogen ion is base. Base
