Acids and Bases

Simply knowing the concentration of an acid or base is often insufficient to understand its actions. The pH relates to the concentration of hydrogen ions in a solution, and the pOH relates to the concentration of the hydroxide ions in the solution. Acids and bases may be strong or weak. There are only a few strong acids and bases, and calculations involving them are always simpler than calculations involving weak acids or bases. A buffer solution provides a means to control the pH of a solution.

The Problems You’ll Work On

In this chapter, you work with acids and bases in the following ways:

check.png Describing acids and bases

check.png Identifying conjugate acids and conjugate bases

check.png Determining pH and pOH for strong and weak acid or base solutions

check.png Doing stoichiometry of titrations

check.png Completing buffer problems

Note: See the Appendix if you need to check the periodic table.

What to Watch Out For

Remember the following when working on acids and bases:
