  3. Perform calculations for and prepare solutions using various concentration units.
    1. Calculate the amount of compound required to prepare a given volume or mass of solution using percent by weight, percent by volume, percent weight per volume, molarity, molality, and parts per million
    2. Prepare a given volume or mass of solution using percent by weight, percent by volume, percent weight per volume, molarity, molality, and parts per million by choosing the appropriate glassware and measurement techniques
  4. Understand and apply concepts of pH.
    1. Identify a sample as acidic or basic using the pH
    2. Calculate the pH of a solution when given concentration information
    3. Perform calculations for and prepare a solution with a pre-determined pH
    4. Perform calculations for and prepare a buffer with a pre-determined pH
  5. Understand and apply concepts of chemical equilibrium.
    1. Discuss and perform calculations pertaining to systems at equilibrium
  6. Understand and are capable of performing wet chemical analysis procedures.
