NaOH Standardization and Titration of an Unknown Organic Acid Overview: Methods for counting the number of molecules in a sample is a major emphasis of laboratory work. In this experiment we will use the method of titration to count the number of acid molecules in a solution. Measuring mass is a relatively easy procedure to do in the lab (although a balance is expensive). Counting the number of particles requires more effort. Molecular counting can be done by setting an unknown amount of a substance

main features of Taylor’s approach to ‘Scientific Management’‚ and what criticisms have been made of it? Do firms use Scientific Management today? A term “Scientific production management” was initially introduced in the 1800s by the famous economist Adam Smith in his book “The Wealth of Nations”(Beechmont ) Later on‚ in 1911‚ American engineer Frederick Taylor made a research in this field and on its’ basis developed key principles that changed factory management and improved economic efficiency. These

ABSTRACT Much has been written and researched about Deming’s ‘total quality management’ (TQM)‚ Follett’s ‘law of situation’‚ and Taylor’s ‘scientific management’. Yet‚ these management scholars differ in their organizational and strategic leadership abilities and practices and remained in three different corners of a triangle. Though the differences in their thinking may be attributed to the changing nature of management as a discipline over a period of time and consequent changes in the fractionalized

HALLMARKS OF SCIENTIFIC RESEARCH Successful managerial decisions are seldom made on hunches or on trail and error method. The sound and effective decisions are always made on the basis of scientific research. Scientific research focuses on solving problems in a step _by _step logical‚ organized and rigorous manner in each step of research viz.‚ identifying problem‚ gathering data‚ analyzing it and in arriving at a valid conclusion. Organizations may not always be involved in the scientific research

Chemistry Lab Report on standardization of acid and bases. Purpose: To prepare standardize solution of sodium hydroxide and to determine the concentration of unknown sulfuric acid solution. Data and Calculations: This experiment is divided into two parts (Part A and Part B). In the first part of experiment‚ the standardize solution of sodium hydroxide is prepared by titrating it with base Potassium hydrogen phthalate (KHP). The indicator Phenolphthalein is used to determine that whether titration

Introduction At the beginning of the year 2010‚ Scientific Glass Inc. (SG) was enjoying rapid growth‚ high customer satisfaction and plans of international expansion. However‚ problems with its inventory management processes had become apparent and the company’s need for a more effective way to manage its inventory was urgent‚ to say the least. Ava Beane was hired to address this very issue. Beane’s goal was to maintain the company’s service level or "fill rate" of 99% while decreasing "underage"

FIS 30500 Scientific Working Groups The purpose of the Scientific Working Groups is to improve practices and build standards. So far there are 24 Scientific Working Groups in various disciplines as of January 2012. There are five interesting ones that will be discussed. Each of the 24 working groups has scientists working within that specific field. Those scientists are often Federal‚ state‚ or local government forensic laboratory scientists‚ but not all. They are experts in their fields. Facial

The Scientific Method in Relation to Fingerprinting Although no one scientist is recognized as the inventor of the scientific method‚ its use in the scientific community believes to date back to 384-322 B.C. During this time‚ Aristotle recognized the importance of deriving reliable knowledge based on observation. As time progressed to the 1200s‚ Roger Bacon acknowledged the significance of the repeating cycle of observation‚ hypothesis‚ experimentation and verification‚ a scientific method that
