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; and

• 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; and physical and chemical properties of milk and other foods.

Assessment
