Case Study: Titration of Wood Ash
Titration experiments are commonly performed in general chemistry courses to demonstrate technique and to understand acid/base chemistry. Typical titration experiments involve the titration of an acid with a standardized solution of a base. Acids can be benign, such as acetic acid, or more toxic, such as oxalic acid. The experiment outlined in this case study is designed to replace experiments utilizing oxalic acid, an acid with high human health hazards. The wood ash titration also allows students to consider using renewable feedstocks for chemical reactions and processes.
