into several methods of analysis according to the process of the final measurements: 1. Volumetric Analysis It deals with determination the concentration of a solution by titration against a solution of known concentration (standard). 2. Gravimetric Analysis In whichthe substance being determined is converted into an insoluble precipitate which is collected and weighed 3. Instrumental Analysis Determination of a final form by measuring some physical properties that is quantitatively related

MODULE 1: THE CHEMICAL EARTH 3.1.1: Elements in Earth are present mostly as compounds because of interactions at the atomic level * Identify that matter is made of particles that are continuously moving and interacting Matter: anything that has mass and occupies space. Exists in three different states: solid (s)‚ liquid (l) and gas (g) The Particle Theory: “All matter is made up of small‚ indivisible particles called atoms that are continuously moving” | Solid | Liquid | Gas | Particle

Core Module 1: The Chemical Earth Contextual Outline The Earth includes a clearly identifiable biosphere‚ lithosphere‚ hydrosphere and atmosphere. All of these are mixtures of thousands of substances and the use of this pool of resources requires the separation of useful substances. The processes of separation will be determined by the physical and chemical properties of the substances. In order to use the Earth’s resources effectively and efficiently‚ it is necessary to understand the properties

will have a sharp melting point and its mp & bp will not change after further attempts at purification. Impurities can lower or raise bp‚ but only lower mp. Density = mass/volume – pure substances have characteristic densities – eg glass. Gravimetric Analysis This is a method used to determine the composition by mass of a substance. • Mining – determine the % of a mineral in an ore deposit • Quality control of products •

Chemistry 2202 Review Final Exam Chapter 2: The Mole 1. Isotope – atoms of an element that have the same number of protons but different numbers of neutrons. Ex. The three forms of oxygen are called oxygen-16‚ oxygen-17‚ and oxygen-18. They all have 8 electrons and are written as 16/8 O (8 protons + 8 neutrons)‚ 17/8 O (8 protons + 9 neutrons)‚ and 18/8 O (8 protons + 10 neutrons). 2. 3. Mass Number – the sum of the protons and neutrons in the nucleus of one atom of a particular

Centrifugal pumps uses OF CENTRIFUGAL PUMPS: The applications of centrifugal pumps are numerous; however‚ these pumps are most often used in buildings for the following purposes: To pump the general water supply. This includes both the overhead and pneumatic tank systems. In general water supply systems where the pump takes off directly from the city pressure main or where no suction lift is required‚ a centrifugal pump can be used. When a centrifugal pump is being used with a suction
