TEXTILE CHEMISTRY

Textile Chemistry 1. Is an applied form of chemistry Textile chemistry is primarily an applied form of chemistry. It is a highly specialized field that applies the principles of the basic fields of chemistry to the understanding of textile materials and to their functional and esthetic modification into useful and desirable items. Textile materials are […]

POLYMERS AS USEFUL MATERIAL

1) Introduction A polymer is a large molecule (macromolecule) composed of repeating structural units typically connected by covalent chemical bonds. While polymer in popular usage suggests plastic, the term actually refers to a large class of natural and synthetic materials with a wide variety of properties. Natural polymeric materials such as shellac, amber, and natural […]

OPIOID DRUGS & ANTIALLERGIC DRUGS

What are drugs or medicines? Drugs are chemical substances of low molecular mass. These interact with the macromolecular targets (carbohydrates, proteins, nucleic acids and lipids) to produce a biological response. If the biological response is curative and useful then these chemicals are called medicines and are used for the treatment, diagnosis and prevention of diseases. […]

MAGNETIC & SPECTRAL PROPERTIES OF COORDINATE COMPLEXES

INTRODUCTION What Is A Coordination Compound? A coordination complex is the product of a Lewis acid-base reaction in which neutral molecules or anions (called ligands) bond to a central metal atom (or ion) by coordinate covalent bonds. Ligands are Lewis bases – they contain at least one pair of electrons to donate to a metal […]

ELECTROLYSIS

Electrolysis In chemistry and manufacturing, electrolysis is a method of separating chemically bonded elements and compounds by passing an electric current through them. History · 1800 – William Nicholson and Johann Ritter decomposed water into hydrogen and oxygen. 1807 – Potassium Permangenate was discovered by Sir Humphry Davy Overviews Electrolysis involves the passage of an […]

ARRHENIUS THEORY OF IONISATION

Arrhenius theory of ionization and its factors Arrhenius theory One of the properties that acids and bases have in common is that they are electrolytes–they form ions when they dissolve in water. Svante Arrhenius, a Swedish chemist who received a Nobel prize in 1903 for his work on electrolytes, focused on what ions were formed […]
