Liquid Gold “The sounds of gunshots rang out throughout the town‚ piercing the veil of quiet like a hot knife through butter. Bushranger PJ Sebastian winced at the sound of every shot‚ keeping his fingers crossed and begging that none of the shots hit their mark. Desperately‚ he limped towards the tree line‚ as if he had any other choice in the matter‚ begging that the tall‚ menacing oak and gum trees could protect him from his assailant. Blood was pouring out of his thigh. He clutched at the wound

High Performance Liquid Chromatography (HPLC) Instructor: Dr. Hüseyin BOZKURT High Performance Liquid Chromatography (HPLC) is one mode of chromatography‚ the most widely used analytical technique. Chromatographic processes can be defined as separation techniques involving mass-transfer between stationary and mobile phases. Present day liquid chromatography that generally utilizes very small packing particles and a relatively high pressure is referred to as high performance liquid chromatography

other secretaries realized how well the invention worked‚ they flooded Graham with requests for their own supplies. The now-famous woman inventor sold her first batch of "Mistake Out" in 1956‚ and soon she was working full-time to produce and bottle it from her North Dallas home. Her son Michael – who would later achieve fame as a member of the pop group The Monkees – and his friends helped to fill the growing number of orders for Mistake Out. Graham continued experimenting with the makeup of the substance

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

the pH of liquids work. We were able to compare the liquids based on their pH level and determine which liquid was acidic or basic. Our results showed that if something came out to be seven or less‚ according to the pH scale‚ it means that an acid is a substance that donates hydrogen ions. Because of this‚ when an acid is dissolved in water‚ the balance between hydrogen ions and hydroxide ions is shifted. Now there are more hydrogen ions than hydroxide ions in the solution (2). A base can increase

STANDARDIATION OF ACID AND BASE Eunice Ivy B. Gamboa ABSTRACT Solutions of known concentration are prepared by dissolving measured masses of standard acids in distilled water. The concentrations of unknown solutions of sodium hydroxide are determined by titration. An acid solution reacts with a base solution in a "neutralization" reaction. Titrations permit the concentrations of unknown acids/bases to be determined with a high degree of accuracy. In order to analyze unknown acids/bases‚ we must have

Experiment 3: Separation of the Components of a Mixture General Chemistry 101 (CHEM 101)‚ ISP SCUHS Report 2 September 15‚ 2013 Abstract Mixtures are made up of substances or components. If the mixture is fairly uniform in composition‚ properties‚ and its overall appearance‚ it is homogenous. If the component parts are clearly separated‚ it is heterogeneous. In order to identify the components in a mixture‚ methods must be used to sort out the components. However‚ the same methods will not
