Objectives

You have completed this lesson when you can:

1. Name acids and bases from their formulas and derive formulas from names, including:

   • Binary acids

   • Ternary acids derived from polyatomic ions you know: nitrate, phosphate, sulfate, carbonate, chlorate, and acetate

   • Hydroxide bases

   • Ammonia

2. Name salts (ionic compounds) containing oxyanions (listed above) and derive formulas from names

3. Define the term "equivalent" in the context of acid-base chemistry and use the formula of an acid/base to convert between moles and equivalents.

4. Define the term "equivalent mass," explain how it differs from molecular mass, and use equivalent mass in calculations involving amounts of acids and bases.

5. Define "normality," convert between molarity and normality, and use normality in calculations involving amounts of acid and base solutions.

6. Describe the process of a titration using the terms "indicator," "endpoint," "titrant," and "unknown solution" and explain the goal of a titration and how the steps of a titration lead to that goal.

7. Apply the concept of normality to calculate concentrations of solutions in a titration.

8. Use proper lab techniques to perform a titration and use lab data to experimentally determine the equivalent mass of a substance.
