Experiment 11: Acids and Bases General Chemistry I and II Lab Manual Dakota State University page 139 of 232 Experiment 11: Acids and Bases Purpose: To gain experience in the properties of acids and bases Purvey: To sell or provide (and I’ll bet you thought it meant something else, didn’t you?)

So why, then, are acids and bases important enough to warrant their own place in a first year course? Because, when we are talking about acids and bases, we are talking about the chemistry of water-based solutions (typically), and water is of critical importance to us as human beings. Think about it; 70% of the earth is occupied by water. YOUR BODY is 90% water.
