Subject Description

The objective of this subject is to develop a student's ability to:

• apply an understanding of atomic and molecular structure to the properties of elements and compounds;

• explain phase change phenomena in terms of molecular, atomic or ionic interactions;

• use the conventions for chemical symbols, formulae and equations;

• describe the nature of chemical change;

• carry out chemical calculations for a variety of reactions;

• explain the principles of chemical determinations by volumetric and gravimetric methods;

• apply theories of acid and base action and make appropriate calculations;

• apply concepts of oxidation and reduction;

• name and describe basic categories of organic compounds;

• explain properties of organic compounds on the basis of structure and nature of functional groups;

• relate basic principles to the physical and chemical properties of milk and other foods.

The content includes: Nature and structure of matter. Chemical symbols and formulae. Periodic table. Nature of chemical change. Writing chemical equations. Chemical calculations, Stoichiometry. Concentrations of solutions. Acids, bases neutralisation pH, buffers. Oxidation and reduction. Equilibria. Organic chemistry. Physical and chemical properties of milk and other foods.
