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

These functional groups are removed by using a basic solution as shown in (i) below1. The product formed with water is stable only due to resonance‚ but does

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

Educational Preparation in Nursing Grand Canyon University: NRS 430 11/11/2012 Educational Preparation in Nursing With a consistent change in modernizing medicine‚ along with the continuing advancement in technology‚ continuing education in nursing is essential for a variety of reasons. The nurse’s main concern is providing safe‚ efficient‚ and effective patient care with positive patient outcomes. This paper will examine the differences in competencies between nurses prepared at an associate-degree

Preparation of 4-bromoaniline Introduction Aromatic compounds tend to undergo electrophilic aromatic substitutions rather than addition reactions. Substitution of a new group for a hydrogen atom takes place via a resonance-stabilized carbocation. As the benzene ring is quite electron-rich‚ it almost always behaves as a nucleophile in a reaction which means the substitution on benzene occurs by the addition of an electrophile. Substituted benzenes tend to react at predictable positions. Alkyl groups

Ayiyi Grand Canyon University: NRS 430v November 24‚ 2013 Education Preparation Paper There has always been an on going debate in health care‚ as to where the entry into nursing should be‚ this debate continues to divide the field of nursing and has prevented nurses from becoming a more dynamic and united profession (Spencer‚ 2008). The argument that more education translates into better performance is constantly debated. Because there are many

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
