Joscely Garris Professor Vinh Hoang CHEM 1151L – 254 25 October 2013 Preparation of Viscous Solution This report discusses an experiment to study the relationship of solute/solvent and the calculations involved to measure the concentration of the solution. The first experiment to take place is the preparation of a salad dressing using xanthan gum solution‚ water and oil. Commonly used as a food thickening agent‚ Xanthan gum is a large molecule composed of several saccharides linked together

EXPERIMENT 2: SOLUTION PREPARATION AND STANDARDIZATION Submitted by Iris Olaso ______________________________________________________________________________ INTRODUCTION Generally‚ there are two ways in preparing a solution‚ one is by dissolving a weighed amount of solid in a required solvent and the other is by dilution of a concentrated solution into the desired concentration. In diluting concentrated solution‚ the concentration of the diluted solution can be determined by standardization

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

The Preparation of 1- Bromobutane Introduction... Aim : To prepare 1-Bromobutane. Background : The most common way of preparing alkyl halides‚ which are very useful intermediates in syntheses‚ is the replacement of the OH group of an alcohol by a halogen. This replacement is a nucleophilic substitution reaction‚ and alcohols do not undergo nucleophilic substitution reactions because hydroxide ison is strongly basic and a poor leaving group. However‚ alcohols readily undergo
