Lesson 6: Objectives
The purpose of this lesson is to acquaint you with the nomenclature used for acids and bases, with solutions of acids and bases - how they are prepared and how their concentrations are calculated and expressed, and with the procedures and calculations used in a technique called titration, in which solutions of acids and bases are mixed to determine their concentrations.
You have completed this lesson when you can:
1. Name acids (binary and oxy-acids) and bases (metallic hydroxides and ammonia) given their formulas, and vice versa.
2. Given the formula of an oxyanion or salt, name it. Given the name, write the formula.
3. Define an equivalent and calculate the number of equivalents of an acid or base given the formula and the number of moles or the concentration and volume of a solution.
4. Define equivalent weight and calculate the equivalent weight of an acid or base given the formula and formula weight.
5. Define normality and calculate the normality of a solution given the formula of the acid or base and the molarity of the solution (or other appropriate information).
6. Calculate the concentration (normality or molarity) of a solution made by diluting a more concentrated solution.
7. Write balanced equations ("molecular" and ionic) for acid-base neutralization reactions.
8. Describe titration and explain what it is used for.
9. Use the proper techniques for performing a simple titration.
10 Calculate the concentration of a solution using titration data.
11. Experimentally determine the equivalent weight or molecular weight of a solid acid using titration data.
