Iron powder will react with cupric sulfate in a onetoone ratio (1 mole to 1 mole). The students will also be able to more easily visualize the size of a mole of iron and copper. The result obtained in this lab usually have less than a one percent error. Fe(s) + CuSO4 (aq) > FeSO4(aq) + Cu(s) Iron powder cupric sulfate ferrous sulfate copper In the reaction‚ iron will be the limiting reagent; it will be completely used up in the reaction. Cupric sulfate will be in excess; not all of it will be used up in the reaction

CASE ONE Two advertising media are being considered for promotion of a product. Radio ads cost $400 each‚ while newspaper ads cost $600 each. The total budget is $7‚200 per week. The total number of ads should be at least 15‚ with at least 2 of each type‚ and there should be no more than 19 ads in total. The company does not want the number of newspaper ads to exceed the number of radio ads by more than 25 percent. Each newspaper ad reaches 6‚000 people‚ 50 percent of whom will respond; while each

EXPERIMENT 8 QUANTITATIVE DETERMINATION IODOMETRIC TITRATION OF COPPER CONCENTRATION IN AQUEOUS SOLUTION B Y RESULTS AND DISCUSSION Considered as moderately weak oxidizing agent‚ Iodine was used for the determination of strong reductants. Standard iodine solutions were found to have smaller electrode potentials as compared with the other oxidants‚ gaining them the advantage of imparting a degree of selectivity essential in the determination of strong reducing agents amid the presence

Chapter 1 Introduction to Quantitative Analysis Teaching Suggestions Teaching Suggestion 1.1: Importance of Qualitative Factors. Section 1.2 gives students an overview of quantitative analysis. In this section‚ a number of qualitative factors‚ including federal legislation and new technology‚ are discussed. Students can be asked to discuss other qualitative factors that could have an impact on quantitative analysis. Waiting lines and project planning can be used as examples.

Introduction: The purpose of this lab will be to investigate the concepts of accuracy and precision for quantitative measurements using density as an example. The density of a sample will be found experimentally and compared to a known value. The relationship of averages and different analysis techniques to percent error will also be explored. Density is a characteristic of a substance which can qualitatively be described as the amount of matter (mass) squeezed into a given space (volume). The
