Introduce the pKa of acids. Discuss it as a way of expressing acid strength other than pH. Show that as the acid strength increases, the pKa becomes smaller. Discuss acid base reactions which occur between: strong acids and strong bases, weak acids and weak bases, strong acids and weak bases, and weak acids and weak bases. Discuss each reaction in terms of Hydronium ion productio and conjugate acids and bases formed.
Present a series of problems which involve calculating the hydronium ion concentration, the hydroxyl ion concentration, the pH and pOH of acid solutions. Determine the acidity of blood and the concentration of ions based on the pH. List and discuss generalizations for acids and bases, strong acids and strong bases.
