Acid and Base Titrations: Preparing Standardized Solutions Introduction: This experiment focuses on titrations of acids and bases. A titration depends on addition of a known volume of solution and is a type of volumetric analysis. Many titrations involve either acid-base reactions or oxidation-reduction reactions. In this experiment we do one of each. We monitor the pH of the reaction with the use of a color indicator. We also learn about the standardization of bases (NaOH) and acids (HCl) which

Donald Clark in his article “10 Reasons to NOT Teach Latin (Reductio ad Absurdum).” Along with a number of others‚ Clark holds the belief that learning Latin‚ a “dead language‚” wastes time. Clark‚ however‚ is wrong. If we truly examine our interaction with Latin‚ and the skills it confers onto us‚ it becomes evident that his opinion does not correspond with reality. Clark sees the language of Latin as solely an advertizing draw private schools use to attract snobbish parents. To Clark‚ studying

Leadership and Power Base Development: Using Power Effectively to Manage Diversity and Job-Related Interdependence in Complex Organizations Barton J. Michelson Mention the word power and what comes to mind? Power is evil‚ corrupt‚ self-serving‚ manipulative‚ hurtful‚ and possibly “America’s last dirty word.”1 These words speak to the dark side of power. There is‚ however‚ a positive face to addressing power acquisition‚ power-base development‚ and power use. The purpose of this article is to consider

Introduction The parade of corporate accounting scandals of the last decade‚ with lion’s share occurring in 2002‚ has developed deep antipathy and distrust towards corporations and their reporting practices‚ and casted doubts on the opinions of audit firms. As majority of these accounting frauds occurred in the US (See Appendix)‚ there was a widely-held view that rules-based accounting standards have allowed failure of large corporations like Enron and World Com‚ since US GAAP is perceived to

The similarities between the Lewis and Clark expedition of 1803 to 1806 and a manned mission to Mars are not immediately obvious. Meriwether Lewis‚ William Clark and their fellow adventurers never had to deal with the problems of cosmic radiation‚ for instance‚ or the osteoporosis and muscle atrophy caused by spending months in zero gravity. And they had a never-ending supply of air. I expected that a comparison between their trip across the West and a potential space mission wouldn’t be that useful

CHEMICAL REACTIONS: ACID-BASE BUFFERS Short Overview Acids and bases represent two of the most common classes of compounds. Many studies have been done on these compounds‚ and their reactions are very important. Perhaps the most important reaction is the one in which an acid and base are combined‚ resulting in the formation of water (in aqueous solution) and a salt; this reaction is called neutralization. A buffer solution is a solution that contains both an acid and a salt

ACID BASE IMBALENCE INTRODUCTION The body normally maintains a steady balance between acids‚ produced during metabolism and bases that neutralize and promote the excretion of the acids.Many health problems may lead to acid base imbalance.Patients with Diabetis mellitus ‚COPD‚and kidney disease frequently frequently develop acid base imbalences. Vomiting and diarrhea may also cause acid base imbalance.The kidneys are an essential buffer system for

The Base Ball Pitch - Tom Hando The biomechanics of a movement is slightly different to the physiological principles of it. The biomechanics of a movement‚ is how the forces acting upon an object effects the way the object moves. (FIGURE 1) For example in my movement‚ the baseball pitch‚ in the wind up stage of the pitch‚ the forces acting upon the body is causing hip and knee flexion which results in the knee and hip coming into contact with the chest. Whereas the physiological principles is working

Winstrom Construction was a local Ohio firm that had completed much of the construction at Wright-Patterson Air Force Base. They submitted a bid of $5‚960‚000 with a required deposit of $1‚000‚000. Winstrom had worked previously on a similar project for Peach and had finished it on-time. Don was concerned with the deposit given that Peach would have to supply these
