TITRIMETRIC ANALYSIS 3.7.1. BASIC PRINCIPLES In titrimetric analysis we volumetrically measure the amount of reagent, often called a titrant, required to complete a chemical reaction with the analyte. A generic chemical reaction for titrimetric analysis is ����+����→���������������� Where: a moles of analyte A contained in the sample reacts with t moles of the titrant T in the titrant solution. The reaction is generally carried out in a flask containing the liquid or dissolved sample

CRYSTAL STRUCTURES CRYSTAL STRUCTURES • Have you ever wondered how atoms assemble into solid structures? • How does the density of a material depend on its structures? CRYSTAL STRUCTURES • Solid materials can broadly be classified as crystalline and non crystalline (amorphous) solids. • In crystalline solid the arrangement of atoms is in a periodically repeating manner whereas no such patterns are found in a non-crystalline solid. CRYSTAL STRUCTURES • 2 types of crystalline solids:

demand for the use of industrial chemicals. The use of these chemicals has resulted in great benefits in raising the standard of living, prolonging human life and improving the environment. But as new chemicals are introduced into the marketplace and existing chemicals continue to be used, the environmental and human health impacts of these chemicals have become a concern. Today, there is a much better understanding of the mechanisms that determine how chemical are transported and transformed

Abstract An abstract should be one paragraph of 100-200 words. It summarizes four essential aspects of the experiment or report: the purpose, key findings, main significance, and major conclusions. This information helps readers decide whether they need to read the whole report. Sample Abstract This report presents the separation of a 10%mol ethanol-water mixture with a 28-stage distillation column. Both finite and infinite reflux runs were performed, each at a high supply steam pressure

Atoms are the smallest entities which resemble the properties of an element and cannot be broken down into smaller parts. Molecules are formed when two or more atoms are combined. This formation can happen in a variety of ways. When two oxygen atoms join O2 is formed, and when three oxygen atoms join O3 or ozone is formed. Both of these have different properties. Different atoms can also combine to form molecules. Hydrogen combines with sulfur to form H2S and hydrogen and oxygen also combine

the sentence have the exact same meaning. This still doesn’t mean that it is a language because it can directly translate into English which contradicts the Worf theory of language.) b) The following two equations are examples of complicated chemical equations. It would take a large amount of time and space to translate either of these two into English. 1) Chemistry also has its own rules (grammar) c) Both hydrogen and oxygen are “special” elements that, when written by themselves
