Identification of gases e.g CO2, SO2 and O2. Characteristics test for anions e.g SO42-,SO32-,CO32-,NO-3, Cl–, etc. The anions are negatively change ions examples of anions
Introduction to Qualitative Analysis Test for carbons using H2S, NaOH and NH4OH, Confirmatory Test for the cat ions. Introduction to Qualitative Analysis Qualitative analysis
Aluminum can be obtained as Kaolin, Al2O3.2SiO3.2H2O, cryolite. Na3AlF6, Corundum Al2O3 and mica K2O.Al2O3.6SiO2. NB: the main source of aluminum is bauxite Al2O3.2H2O Extraction
PRELIMINARY PREPARATION Metals are found mixed with earthy materials as ores. Ores are often concentrated and converted to oxides before extraction Concentration of the
SIMPLE MOLECULES AND THEIR SHAPES Covalent Molecules e.g methane, diamond, crystalline solid – their network structure e.g diamond. Simple Molecules and their shapes The
Nuclear Reaction This is the spontaneous emission of radiation that involves the nuclei of radioactive element. Nuclear Fusion This is the process in which
Nuclear Chemistry is an aspect of chemistry that deal with nuclei of atoms. Radioactivity This is the spontaneous emission of radiation by radioactive element such
It is often useful to follow chemical reactions by looking at changes in the oxidation numbers of the atoms in each compound during the reaction.
In chemistry, a compound is a substance that results from a combination of two or more different chemical element s, in such a way that
ISOTOPE Isotopes Definition: Isotopes are atoms with the same number of protons, but differing numbers of neutrons. Isotopes are different forms of a single element.
Atoms are the basic units of matter and the defining structure of elements. Atoms are made up of three particles: protons, neutrons and electrons. Protons
A molecule is the smallest particle in a chemical element or compound that has the chemical properties of that element or compound. Molecules are made
ELEMENTS Element Definition: A chemical element is a substance that cannot be broken down by chemical means. Elements are defined by the number of protons
