Classwork Series and Exercises {Chemistry- SS1}: IUPAC Nomenclacture of Inorganic Compounds and Concept of Oxidation Number

IUPAC Nomenclacture of Inorganic Compounds and Concept of Oxidation Number Oxidation number is the charge on the valency of an element, i.e. Oxidation state = Valency + Charge The valency of metal carries a positive charge, e.g. Na+ while the valency of non-metal carries the negative charge, e.g. Cl- The total oxidation state of any [...]

Classwork Series and Exercises {Chemistry – SS2}: Electrolysis

Chemistry, SS 2 Week: 6 Topic: Electrolysis What is Electrolysis? Ionic substances contain charged particles called ions. For example, lead bromide contains positively charged lead ions and negatively charged bromide ions. Electrolysis is the process by which ionic substances are decomposed (broken down) into simpler substances when an electric current is passed through them. In [...]
