1. The document provides 7 chemistry problems involving calculations of pH, concentrations of products and reactants from acid-base reactions involving strong acids and bases, and identification of types of acids. 2. Problems 1-3 involve calculating the pH of strong acid solutions given molar concentrations. 3. Problems 4-6 require using given volumes, molarities, and extent of ionization to calculate concentrations of products and reactants. 4. Problems 7-9 ask about common weak bases, relationships between types of acids, and identification of more acidic salt solutions.
