Product Description

By: The Flinn Staff

Mix a suspension of milk of magnesia (MOM) with universal indicator, add simulated stomach acid, and observe the dramatic rainbow of colors as the antacid dissolves in the acid! And...it's not over yet! Simply add more acid and watch as the colors continue to change and indicate the reaction of the milk of magnesia with the "stomach acid." An eye-catching, spectacular demonstration to teach solubility, acid-base, and "antacid-testing" consumer chemistry! Teacher Demonstration Notes included. Enough materials are included to perform the demonstration seven times.

Solubility, Ksp, acid-base neutralization, antacids.
Time Required: 15 minutes
Materials Provided: Milk of magnesia (MOM) suspension, hydrochloric acid solution, universal indicator solution, and Beral-type pipets.

  • MOM and pH Video
