This course provides the fundamentals of chemistry as it applies to the water industry. The
intent is to lay the foundation for operators to understand more advanced theories involving
chemical reactions in water. Topics include the theory behind pH, alkalinity and titrations.
These topics are supported by concepts such as chemical equations, equilibriums, acid base
theory and buffering capacity.
Upon completion of Introduction of Water Chemistry, the student should be able to:
- Explain the polar nature of water and its unique properties
- Describe the cycling of water in the environment and the concept of residence time
- List the steps in a general analytical method and explain the things that must be
considered when choosing an analytical method.
- Predict whether a reaction is at equilibrium and write the equilibrium constant
expressionsManipulate chemical reaction equations and the corresponding equilibrium constant
- Define Arrenhius and Bronsted-Lowry acids and bases
- Write acid and base ionization constant reactions and expressions
- Compare the strength of acids and bases
- Relate pH, pOH, [H3O+] and [OH-]
- Discuss the common methods of measuring pH
- Explain the process of titration
- Define alkalinity and outline the method for experimental determination
- Discuss the buffering capacity of water
- Explain the relationship between water quality and water treatment
- Write solubility-product expressions
- Polar nature of water
- Cycling of water and residence time
