How do antacids work? Titration of an Antacid
Michael Garoutte | Wed, 10/05/2022 - 07:08
Heartburn is a very common ailment. Many people rely on antacids such as Tums®, Rolaids®, or Milk of Magnesia to settle their stomachs, but have you ever wondered how those antacids work?
KoolAid and similar drinks as convenient laboratory reagents: The weak acid-strong base titration of citric acid or malic acid
David Cash | Fri, 05/13/2022 - 08:06
The major component of a non-carbonated drink such as KoolAid or a similar beverage is usually a fruit acid, either citric acid or malic acid. The titratable acid (H+) concentration of such drinks has been found to be in the range of 0.02 to 0.04 M. A weak acid-strong base titration of these drinks with 0.1 M NaOH solution is feasible as a student exercise. The use of such drinks as reagents is safe, convenient, and inexpensive. Experiment instructions are included.

Two groups of students, typically, have difficulty with titrations, the first time around. Those that act too rashly and overshoot the endpoint, and those over-cautious ones who they take forever to finish.
