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.
Discuss the pH method for determining acid strength. Show how to compute pH from the concentration of hydronium ions. Introduce the acid ionization constant for acids. Show how to arrive at the constant. Discuss why a strong acid has a particular number and its meaning. Work a few problems
Discuss Arrhenius acid modes. Introduce proton donor and acceptor. Discuss some examples of proton donors and acceptors, and why they are either acid or base molecules. Define monoprotic, diprotic and polyprotic. Show why some may be amphiprotic
Review Bronsted -Lowry acids. Introduce pH of a solution and relate it to the concentration of hydronium ions. Use the water constant Kw= conc. of hydronium x conc. of hydroxide ions to solve for concentration of one of the unknown. Define pH as the negative log of the concentration
