...concentration of pesticides in this case. Given two different substances, it is required to determine if the first solution is an acid or base. It is also mandatory to determine which of the three known cations exist in the second unknown solution based on qualitative analysis. After identifying what each solution is, it is needed to discover the concentration of each solution. Materials Litmus paper, dropper, 15ml of unknown solutions laboratory bottle (2). 15.03ml of NaOH beaker, pipet, volumetric flask, 100 ml of CH3COOH beaker, burette, white paper, bromothymol blue dropper Laboratory bottle, test tube, Na2SO4 wash bottle, Na2CO3 wash bottle, NaOH wash bottle Paper clip, tong, bunsen burner, flint, distilled water beaker, KI laboratory bottle, Ba(NO3)2 laboratory bottle, CuSO4 laboratory bottle, unknown solution laboratory bottle. Procedure Before conducting any experiment, it is important to wear safety goggles to insure protection for the eyes. With the objective of differentiating the two unknown substances, the ideal method to determine which substance is an acid or base was utilizing litmus paper. After a few drops of the first substance, on one half of the litmus paper, no colour change was observed. It was concluded that the second solution would be the acid or base. To determine whether it was an acid or base, a few drops of the solution was applied to the other half of the litmus paper, resulting in a colour change to the colour blue, which indicates that the substance...

...Chemistry 1B Experiment 16 77 16 Qualitative Analysis Introduction The purpose of qualitative analysis is to determine what substances are present in detectable amounts in a sample. This experiment has two parts. In the first part, you will analyze an unknown solution for the presence of seven common ions. In the second part, you will test an unknown solid to determine which of two possible identities is correct. Part I. Spot Tests for Some Common Ions A simple approach to the qualitative analysis of an unknown solution is to test for the presence of each possible ion by adding a reagent which will cause the ion, if it is in the sample, to react in a characteristic way. This method involves a series of “spot” tests, one for each ion, carried out on separate samples of the unknown solution. The difficulty with this way of doing qualitative analysis is that frequently, particularly in complex mixtures, one species may interfere with the analytical test for another. Although interferences are common, there are many ions which can be identified in mixtures by simple spot tests. In this experiment we will use spot tests for the analysis of a mixture which may contain the following commonly encountered ions in solution: CO32– SO42– PO43– SCN Cl – – carbonate sulfate phosphate thiocyanate chloride acetate ammonium C2H3O2– NH4+ 78 Chemistry 1B Experiment 16 The procedures we involve simple acid-base, precipitation, complex ion formation or oxidation-reduction...

...www.studyguide.pk Acids, Bases and Salts THE THEORY of ACIDS and ALKALIS and a few technical terms: o Acids are substances that form hydrogen ions (H+(aq)) when dissolved in water eg hydrochloric acid HCl gives H+(aq) and Cl-(aq) ions, sulphuric acid H2SO4 gives 2H+(aq) and SO42- ions and nitric acid HNO3 gives H+(aq) and NO3-(aq) ions. o Alkalis are substances that form hydroxide ions (OH-(aq)) in water eg sodium hydroxide NaOH gives Na+(aq) and OH-(aq) ions, calcium hydroxide Ca(OH)2 gives Ca2+(aq) and 2OH-(aq) ions. Note: an alkali is a base soluble in water. o In water, there are trace quantities of H+ and OH- ions BUT they are of equal concentration and so water is neutral. o In acid solutions there are more H+ ions than OH- ions. o In alkaline solution there are more OH- ions than H+ ions. o Acids dissociate to different extents in aqueous solution. Acids that dissociate to a large extent are strong electrolytes and strong acids. In contrast, acids that dissociate only to a small extent are weak acids and weak electrolytes In a similar manner, bases can be strong or weak depending on the extent to which they dissociate and produce OH– ions in solution. Most metal hydroxides are strong electrolytes and strong bases. Ammonia, NH3, is a weak electrolyte and weak base. o BASES eg oxides and hydroxides are substances that react and neutralise acids to form salts and water. Bases which are soluble in water are called alkalis. Acids Some common acids are listed...

...the input sources from the employees because this is the identified area where creativity does not exist in the desired way. Leadership teams must recognize that the survey indicates employees do not feel they have the freedom to provide creative input therefore; leadership team members become part of the problem. Mat and Razak (2011) state, “Identification of success or failure of innovation can be done through implementation phase” (p. 217). As a result, the problem itself lies within the leadership team members rather than the employees of Best Snacks. Based on this analysis of the Best Snacks survey results and the desired results of the organizational direction, the basis of investigation for the problems with creativity begin with the leadership team members. This requires an analysis of development skills of leadership team members and leadership skills. Within those two components, the analysis entails assessment of how these members lead...

...Chemistry Notes 2010 Core Module 1: Production of Materials Contextual Outline Humans have always exploited their natural environment for all their needs including food, clothing and shelter. As the cultural development of humans continued, they looked for a greater variety of materials to cater for their needs. The twentieth century saw an explosion in both the use of traditional materials and in the research for development of a wider range of materials to satisfy technological developments. Added to this was a reduction in availability of the traditional resources to supply the increasing world population. Chemists and chemical engineers continue to play a pivotal role in the search for new sources of traditional materials such as those from the petrochemical industry. As the fossil organic reserves dwindle, new sources of the organic chemicals presently used have to be found. In addition, chemists are continually searching for compounds to be used in the design and production of new materials to replace those that have been deemed no longer satisfactory for needs. This module increases students’ understanding of the implications of chemistry for society and the environment and the current issues, research and developments in chemistry. 1.1 Construct word and balanced formulae equations of all chemical reactions as they are encountered in this module: • Acid reactions: o acid (aq) + base (aq) salt (aq) + water (l) o acid (aq) + active metal (s) salt (aq) + hydrogen (g)...

...Eleanor Francis Francis 1 MEDC 5310 Carol Richardson October 17, 2013 An Analysis of the Ideology and Messages About Culture in Prime Time Television Seven days a week, 24 hours a day there is something to watch on television. There are reality shows, newscasts, news programs, dramas, sitcoms, the list is endless. The Big Bang Theory, The Millers, Law & Order: SVU, and Blue Bloods are all part of the prime time lineup of shows throughout any given week. The Big Bang Theory, airs on CBS and was created by Chuck Lorre and Bill Prady. It is the story of two brilliant physicists that work at CalTech in Pasadena, CA. Leonard Hofstadter and Sheldon Cooper are co-workers, best friends and roommates. Sheldon is “regimented, deeply eccentric, and non-conventional” in his thinking which is a consistent hardship on the relationship between these two friends (“Plot Summary”). They are friends with colleagues Howard Wolowitz, a mechanical engineer, and Rajesh Koothrappali, an Indian immigrant who works as an astrophysicist. The foursome are “self-professed nerds, [with] little or no luck with popular women” (“Plot Summary”). A neighbor, Penny, is of average mind but compared to this brilliant squad she’s made to seem of less than average intelligence. Leonard’s goal is to get Penny to be his girlfriend. Immediately following Big Bang is The Millers created by Greg Garcia and starring Will Arnett. Arnett plays the part of Nathan, a single reporter who has...

AGAIN AND AGAIN Chapter I. THE PICTURE OF DEATH THEY killed Doc Savage on Saturday. It was chilly that afternoon, with a little snow falling, and the snow as hard as salt particles. The wind had a hissing strength; it pounced on pedestrians and shook their overcoats and flapped their hat brims. Soldiers on the streets, and sailors in their winter-issue peajackets, blew steam on their fingers. The man with the red hat and the blue armband with the yellow cross was not used to the cold, or to the bite that winter has in New York, close to the sea. He cursed the weather fluently, with the slightly accented voice of a man who can speak several languages. His red hat and blue-yellow-cross armband, incidentally, was his own idea of a disguise. Dress in a bizarre outfit, he believed, and people wouldn't be able to recognize you when you dressed in ordinary clothes. He crossed Fifth Avenue and went into a restaurant, one of those white-enamel-and-chrome quick-eat places. “Mug one and save the cow,” he told the waiter. He grinned a little when he said that, for he liked to show his acquaintance with the local vernacular, in any part of the world where he happened to be. Soon after he got his coffee black another man came in. This fellow looked very much a gentleman. He could have been a clerk...
