Introduction to Qualitative Analysis Test for carbons using H2S, NaOH and NH4OH, Confirmatory Test for the cat ions. What is Qualitative Analysis? Qualitative analysis involves examination of colour, flame test, effect of heat and confirmatory test for cat ion and…
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 Aluminum can be found in clay and rocks, but due to their high silica content, they…
Metals are found mixed with earthy materials as ores. Ores are often Concentration of the ore can be done by any of the following ways: Roasting in Air The ore is roasted in air to convert to an oxide. There…
The atoms of metals are held together in crystal lattice by metallic bonds Properties Factors affecting the formation of metal strength The Valence Electrons Intermolecular Bonding This is the type of chemical bonding which can be found in some molecular…
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 factors that is responsible for the shape of simple covalent molecules are Covalent Molecules Let consider…
Nuclear Reaction This is the spontaneous emission of radiation that involves the nuclei of radioactive element. Nuclear Fusion This is the process in which two or more light nuclei of elements combine together to form a heavier nucleus with release…
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 as Thorium, Uranium etc. Characteristics of Nuclear Chemistry Types of Radiation There are three (3)…
It has a functional group of NH2. MOLECULAR FORMULAR/STRUCTURE It has a general molecular formula of RNH2 or structure of R – N – H H PREPARATION: They are derivatives of ammonia where one or more hydrogen atoms have been…
Carbohydrates are naturally occurring organic compounds containing carbon, hydrogen and oxygenwith oxygen in the ratio 1:2 as in water. The general molelcular formula of carbohydrates is Cx(H2O)y or CxH2yOy. Carbohydrates are generally polydroxyl aldehydes, ketones or any compound that on…

Alkynes are the homologous series of unsaturated hydrocarbon with a general molecular formua CnH2n-2. Alkynes show a high degree of unsaturation than alkenes, hence,t hey are chemically more reactive than the corresponding alkenes or alkanes. Examples are : H H…
Unsaturated Hydrocarbons These are hydrocarbons in which carbon atoms join with each other by multiple bonds. The multiple bond can be a double bond, e.g Alkene or a triple bond, e.g Alkyne. H – C = C – H H…
Saturated hydrocarbons are hydrocarbons consisting of carbon chains with single bonds between them, in which carbon joins with another carbon by a single covalent bond, e.g Alkanes ( like ethane C2H6, propane C3H8 ) H H HHH H – C …
