Acid in the human stomach When people refer to acid they usually see it as a corrosive liquid that can dissolve metals or change the color of a substance. So they think of acid as a dangerous matter for the body and believe it can easily dissolve your skin. What I have previously listed are indeed properties of certain acids‚ such as Hydrofluoric Acid which can cause irreversible tissue damage if it comes in contact with skin‚ but not all acids are this strong. As a matter of fact what a lot of

(Fe3+ ) form. Ferric form is not usually absorbed in the body. In the stomach‚ there is low pH of 2 due to presence of gastric acids such as Hydrochloric and Ascorbic acids. These acids provide an acidic environment for reduction of ferric iron to ferrous (Fe2+). Ferrous iron can be absorbed in the body system. As in following equation of iron (iii) reaction with Ascorbic acid ‚ the product is iron (ii) chloride which is soluble 2 Fe3+ (s) + C6 H8 O6 (aq) → 2 Fe2+ (aq) + C6 H6 O6 (aq) + 2 H (aq)+

Abstract Fisher Reaction is a special type of esterification that uses an acid catalyst to reflux Carboxylic acid and Alcohol. The product Ester is in equilibrium to the reactants acid and alcohol. Ester is responsible for the smell and aroma of different fruits. After using the Fisher reaction‚ a combination of techniques is used to separate the product. Introduction Esters are naturally occurring compounds that possess a distinctive odor. It is responsible for the smell of different fruits

LABORATORY EXERCISE 8-A: Preparation of Bacterial Smear and Simple Staining I. INTRODUCTION Bacterial smears are prepared for the purpose of viewing microorganisms under the microscope. Visualization of microorganisms in the living state is very difficult‚ not just because they are minute‚ but because they are transparent and almost colorless when suspended in an aqueous medium. A bacterial smear is a dried preparation of bacterial cells on a glass slide. Smears may be made from a dry culture

Preparation of t-Butyl-Chloride March 8 & 15‚ 2012 Theory: Alkyl halides can be synthesized when alcohols react with hydrogen halides. An alkyl halide is a halogen-substituted alkane‚ and a hydrogen halide is a compound consisting of a hydrogen bonded to a halogen (H-X). Alkyl halides are classified as primary‚ secondary‚ or tertiary depending on the number of alkyl substituents directly attached to the carbon bearing the halogen atom. The purpose of this laboratory experiment was to prepare
