“Metallurgy” is an important chapter for ICSE chemistry class 10 Semester 2 examination 2022. This chapter includes the extraction of aluminum from bauxite ore by Baeyer’s process. It is suggested to study the following topics in detail before the attempt the sample paper.
- Occurrence of metals in nature: Mineral and ore – Meaning only.
- Common ores of iron, aluminium and
zinc. - Extraction of Aluminium.
- Chemical method for purifying bauxite
by using NaOH – Baeyer’s Process. - Electrolytic extraction – Hall Heroult’s
process:
Structure of electrolytic cell – the
various components as part of the
electrolyte, electrodes, and electrode
reactions. - Alloys
Definition, alloys of Aluminium (only
constituent elements), properties, and uses.
