Aims and Objectives of the Experiment

The main objective of this experiment is to determine the concentration of different substances. This is achieved by determining the end point(s) of different titrations using the automated potentiometric titrator. These points are known as equivalence points. The units of measurement are the standard units used in titrations i.e. Molarity (moles/liter) of substances used while the quantities of these substances are measured in mL (milliliter).

Theory and Principles

Potentiometric titration is a volumetric method which measures the potential between two electrodes, namely reference and indicator, with the change in the volume of the reagent that is added, known as the titrant. ...

Introduction

Waste is generated as a result of a lot of physical, chemical, and biological processes. Dumping it at some appropriate place is one option. However, ecological effects of throwing away waste products are becoming a serious concern these days. In order to minimize waste, the best strategy is to transform it into valuable products . Plenty of research studies have been carried out to utilize waste effectively. The aim of this report is analysis of the proposed methods for the utilization of common forms of wastes for useful purposes. We also recommend better alternatives to help create a lesser negative ...

Introduction

XX century was characterized with the significant technological progress, which has improved the life of people. Numerous products and services became available, labor and domestic life became easier and more comfortable. However, waste problem is the other side of the technological progress. The solid, liquid and gas waste are formed, and thus land, natural water and air quality degrade. Therefore, in XXI century the research efforts are dedicated to development of methods for sustainable use of water, gas, and solid resources. Wastewater polluted with dye residuals originate from textile, leather and food industry. These industries produce goods that ...

Chemistry examines major ways of how matter is classified and described, this includes the principle of the composition of elements, compounds, and mixtures (Saint-Jalmes 836). Principle of the physical state includes gas, liquid, and solids. Gas, liquid, and solids are generally referred to as observable properties of matter, hence known as states of matter. A gas has no constant volume and shape while in liquid volume depends on the shape of the container they are placed in ("Macromolecular Organic Matter Working Group Report" 39-50). Solids have defined volume and shape. Gases have large intermolecular spacing than the liquids, and ...

Literature review

In the history of the construction of sea structures in oil exploration, load and corrosion together with how those structures will be maintained have always posed a scientific nightmare. Chamberlain, Adam and other authors in a scientific journal illustrate that for a good design of an onshore structure, there should be a right proportion of the ingredients in order for the structure to give maximum life service. They all agreed that in order to achieve this, keen interest should be paid to the permeability, strength, and durability of the mixture. Finally, they added that for effective control of corrosion, ...

Introduction

The Ancient societies have been associated with certain remarkable discoveries that have had significant positive effects on the contemporary society (Lancaster et al 708). Most of these discoveries have influenced various aspects of development in the current generation. For instance, the discovery of medicine by certain ancient scholars has had positive influence on the manner in which medical services are provided by the current generation. Besides, discoveries made on engineering and architectural activities by ancient communities such as the Roman Empire are still being appreciated by a significant number of conventional development stakeholders. The Ancient Roman, particularly, is credited ...

Abstract

This article examines the types of drugs, their effects, and how they influence sex crime. Many people who commit crimes are either under the influence of alcohol or drugs. There seems to be a connection between drugs and offenses such as sexual assault, rape among others. Various drugs have different dangers associated with them. Sedative drugs slow down the way the brain and the body operate, stimulant drugs increase energy and keep people alert while hallucinogenic drugs may lead to very disturbing experiences and expose the user to dangerous behavior. Moreover, individuals who are under the influence of narcotics ...
