Course Info

About this Course

This subject will provide the student with an introduction to basic chemistry concepts relevant to environmental health. Topics include matter and the structure of atoms, the periodic table, compounds, chemical symbols, balancing equations, formulae, acid-base and redox reactions, together with calculations based on formulae and chemical equations. The theory of volumetric analysis, molarity and calculations based on concentration of solutions is discussed. Acid base equilibria, pH and pOH, and buffers will be considered.
