...Measurement of Fe2+ in Iron Pills Redox Titration Purpose: You will prepare and standardize a potassium permanganate solution and use it to determine the amount of iron, specifically Fe2+, in iron pills. Overview: Titration is the volumetric measurement of a solution of known concentration when it reacts completely with a measured volume or mass of another substance. In the first part of this experiment, the potassium permanganate solution, the titrant, is standardized, by quantitatively reacting it with iron (II) ammonium sulfate hexahydrate, Fe(NH4)2(SO4)2•6H2O (abbreviated FAS). The second part of the lab uses the standardized potassium permanganate to determine the amount of the analyte, also iron (II), in iron supplement pills. In this experiment, a purple-colored solution of potassium permanganate, KMnO4, with an approximate concentration of 0.02 M will be added to solutions containing Fe2+ ions. In redox titration the chemical reaction is an oxidation-reduction reaction with electrons transferred from one species to another. The total number of electrons lost in the oxidation half-reaction is equal to the total number of electrons gained in the reduction half-reaction. The permanganate ion, MnO4-, is a strong oxidizing agent which causes the Fe2+ to be oxidized to Fe3+ ions. The manganese gains five electrons and is reduced from a 7+ oxidation state in the permanganate ion to form colorless Mn2+ ions. The Fe2+ loses one electron as it is oxidized to Fe3+...

...Clean Water Project Report Day 1- “The Balanced Equation” Documentary Notes In the documentary, “The Balanced Equation”, a group of high school girls tells their story of traveling to Kenya and the Dominican Republic to investigate and learn more about issues dealing with water in developing countries. The girls focus primarily on problems with water that exist in these countries and the water filtration systems being provided. According to the video, approximately 3.5 million people die from water-related illnesses each year, and over 800 million people do not have access to clean water today. The girls discover that portable point-of-use filtration devices are given to those in developing countries who don’t have access to clean water. Permanent water solutions, such as digging wells, have been tried, but often fail due to lack of maintenance and education. Wells often become contaminated with runoff water among other issues, so over 50% of these permanent solutions fail after 5 years. Instead, point-of-use water systems are distributed since they are portable and can be used at home. The girl’s spent their first night of their adventure in...

...CHM 1101 Introductory Chemistry Dawn Fox Medeba Uzzi August, 2007 Compiled and edited by Medeba Uzzi Authors’ Note This document is an initiative by the authors in an attempt to deal with what they think may be one of the reasons contributing to the relatively high failure rate in the introductory Chemistry course (CHM 1101) at the University of Guyana. It was brought to our attention that many first year students taking CHM 1101 are unable to efficiently cope with the frenetic pace of the Semester system and even less able to deal comprehensively with the large content in CHM 1101. It is hoped that by providing this paper, students will not need to make lots of notes in lectures and so they can focus on grasping the concepts taught. The document is meant to be a guide to the topics covered in CHM 1101 and is by no means exhaustive. Students are still required to attend classes regularly and punctually and to engage meaningfully in lectures and tutorials. Further, supplemental reading of these topics in any good General Chemistry text is expected. Dawn Fox Medeba Uzzi 2 SECTION 1 – Modules A – D: section deals with the foundation for chemistry. It introduces students to matter & its classification, Atom & its structure, Periodic table and chemical rxns. Introduction to Science and Measurement What is Chemistry? – Chemistry is the study of matter and its transformations Natural sciences refer to the systematic study of the natural world (our...

The learners have also discovered that cells divide to produce new cells by mitosis and meiosis. They have understood that meiosis is an early step in sexual reproduction that leads to variation. Students have been introduced to genetics to be able to appreciate evolutionary differences among species. Learners have also found out that biodiversity is the collective variety of species living in an ecosystem, and by studying the ecosystem; they have come across the various cycling of materials and energy transformation. DRAFT April 29, 2014 All modules in Grade 9 Unit 1-Living Things and Their Environment present student-centered activities that will allow the learners to discover and develop concepts that they may consider useful to their everyday life. At the end of each lesson, key concepts are provided for the students to grasp ideas and information that they will remember even after they have left school. Instructional activities are designed to build up the students’ knowledge, understanding, skills, and ability to transfer...

...1. INTRODUCTION 1.1 Introduction to Nestle Nestlé was founded in 1867 on the shores of Lake Geneva in Vevey, Switzerland and its first product was “Farine Lactée Nestlé”, an infant cereal specially formulated by Henri Nestlé to provide and improve infant nutrition. From its first historic merger with the Anglo-Swiss Condensed Milk Company in 1905, Nestlé has grown to become the world’s largest and most diversified food Company, and is about twice the size of its nearest competitor in the food and beverages sector. Nestlé’s activities contribute to and nurture the sustainable economic development of people, communities and nations. Above all, Nestlé is dedicated to bringing the joy of ‘Good Food, Good Life’ to people throughout their lives, throughout the world. 1.2 History Of Nestle * The Nestlé Company was Henri Nestlé's search for a healthy, economical alternative to breastfeeding for mothers who could not feed their infants at the breast. * The Company formed by the 1905 merger was called the Nestlé and Anglo- Swiss Milk Company. The close of World War II marked the beginning of the most dynamic phase of Nestlé's history. Throughout this period, Nestlé's growth was based on its policy of diversifying within the food sector to meet the needs of consumers. * In 1947, Nestlé merged with Alimentana S.A., the manufacturer of Maggi seasonings and soups, becoming Nestlé Alimentana Company. After the agreement with L’Oreal in 1974, Nestlé's overall position...

...A Review of Literature Related to Oil Spill Dispersants 1997-2008 for Prince William Sound Regional Citizens’ Advisory Council (PWSRCAC) Anchorage, Alaska by Merv Fingas Spill Science Edmonton, Alberta PWSRCAC Contract Number - 955.08.03 Disclaimer: The opinions expressed in this PWSRCAC-commissioned report are not necessarily those of PWSRCAC September, 2008 ii Abstract This report is a review of the literature on oil spill dispersants published from 1997 to August, 2008. The report identifies and focusses on recent advances in dispersant effectiveness, toxicity, and biodegradation. Other topics such as application, use, behaviour and fate are also covered. The prime motivation for using dispersants is to reduce the impact of oil on shorelines, thus the application must be successful and effectiveness high. As some oil would come ashore, discussion remains on what effectiveness is required to significantly reduce the shoreline impact. A major issue is the actual effectiveness during spills so that these values can be used in estimates for the future. The second motivation for using dispersants is to reduce the impact on birds and mammals on the water surface. The benefits of using dispersants to reduce impacts on wildlife still remain unknown. The third motivation for using dispersants is to promote the biodegradation of oil in the water column. The effect of dispersants on biodegradation is still a matter of dispute. Some papers state that dispersants inhibit...
