Review determination of H+ and OH- concentration using the ionization constant for water as 1 x 10^-14. Determine the H+ concentration at equilibrium when given the OH- concentration, and the OH- when given the H+.
Introduce the pH units to determine acidity and alkalinity. Indicate 7 as neutral, 0 to 7 readings as acidic, and 7 to 14 readings as basic (alkaline). Discuss and view the pH of a few common household products
