    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

    A. Title – Acid-Base Extraction with Separatory Funnel B. Introduction – The main objective of the experiment was the extract an acid‚ a base‚ and a neutral compound from a 2:1:1 compound of benzoic acid‚ p-nitroaniline‚ and azobenzene. In theory‚ an extraction technique based on phase distribution should allow two immiscible solvents to separate with a portion of the solute distributed into each. Using a separatory funnel‚ acids were extracted with bases (NaOH)‚ and bases were extracted

    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

    isomers of α-phenylcinnamic acid. This was accomplished by refluxing benzaldehyde‚ phenylacetic acidacetic anhydride and triethylamine as a base. The chemical equation of a Perkin Reaction can be seen below. The reaction mechanism for the synthesis of α-phenylcinnamic acid is shown below: Results: Theoretical Yield Therefore‚ phenylacetic acid is the limiting reagent. Table 1.

    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

    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

    The Cause and Effects of Acid Mine Drainage INTRODUCTION Imagine going fishing on a cool Autumn day‚ the trees are all different shades of orange‚ brown and red and the birds are singing their beautiful songs‚ but their is a serious problem because when you arrive at the river all plant and animal life are gone. This is by no means a recent phenomenon. This is due to the effects of acid rock drainage (ARD). This is a problem that has been occurring since ancient times‚ but it was not until

    benzoic acid mixture was measured to be 2.075 grams. Following being dried for a week the mass of benzocaine was recorded to be 0.250 grams‚ and benzoic acid was recorded to be 0.600 grams. The melting point range of benzocaine was measured to be 89.5°C-91.5°C‚ while benzoic acid’s melting point range was measured to be 129°C-131.3°C. The percent mass recovered was calculated to be 40.96% for the experiment. Table 1 illustrates the collected information. Starting Mass of Benzocaine/Benzoic Acid: 2.075

    By: Jayquan S Salmond Out of all the amino acids‚ 8 are classified as essential amino acids. The body finds it hard to combine them with other compounds at a normal level to assist in adequate growth. The 8 are known as phenylalanine‚ valine‚ threonine‚ tryptophan‚ isoleucine‚ methionine‚ leucine‚ and lysine. When the isoleucine‚ leucine‚ and valine are grouped they are called BCAA or branched-chain amino acids. 1/3 of the body’s skeletal muscles are made up of BCAA. Skeletal muscles are
