    Introduction to Acids Base chemistry Purpose How to determine the constant equilibrium of an acid‚ Ka? How to evaluate the concentration (M) of an acid? In “part A” experiment‚ we would test the PH of different concentration of acetic acid (a weak acid which partially dissociated in water) with a PH probe. After we got the PH‚ we could find out the concentration of H+ by applying the relationship pH = -log [H+]. Having the determined value of [H+] of a weak acid with a known molar concentration

    Abstract The purpose of this experiment was to perform a liquid-liquid extraction method to extract the caffeine from the tea bags that were provided‚ and then recrystallize the caffeine. The solvents used in the experiment were an aqueous sodium carbonate and dichloromethane (DCM). Anhydrous calcium chloride pellets were used to dry the solution and emulsion layer and the DCM was then decanted. After washing the anhydrous calcium chloride pellets with more DCM‚ the solvent was evaporated‚ leaving

    Acid-Base Titration Background Information A titration is a controlled addition of one substance into another substance. In an acid-base titration‚ the experimenter will add a base of known concentration to an acid of unknown concentration (or vice-versa). The goal of the titration is usually to use the substance of known concentration to determine the concentration of the other substance. In order to run a titration‚ the following materials are needed: • A buret filled with the base (or acid) of

    Lab Report Acids and Alkalis: Chemistry of Neutralization and Salt Formation Introduction: An acid is a group of chemicals. Acids are positively charged ions‚ they are liquid and are solutions of pure compounds in water. If you want to know if something is an acid‚ you can test it by using litmus paper. Acids will turn litmus paper red‚ whilst alkalis will turn it blue. Alkalis are negatively charged ions and are usually solid. Aim: To find out how much of different acids is needed to neutralize

    Amino acids are the building blocks of proteins. They band together in chains to form the stuff from which your life is born. Think of amino acids as Legos for your life. It’s a two-step process: Amino acids get together and form peptides or polypeptides. It is from these groupings that proteins are made. And there’s not just one kind of amino acid. A total of 20 different kinds of amino acids form proteins. The kinds of amino acids determine the shape of the proteins formed. Commonly recognized
