Product Details

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 MOM with the “stomach acid.” An eye-catching, spectacular demonstration to teach solubility, acid–base and “antacid-testing” consumer chemistry! Teacher Demonstration Notes included. 

Concepts: Solubility, Ksp, acid–base neutralization, antacids.
Time Required: 15 minutes


Materials Included in Kit: 
Hydrochloric acid solution, 3 M, 250 mL
Milk of magnesia, 150 mL
Universal indicator solution, 50 mL
Pipet, Beral-type, thin stem, 15

Performance Expectations

MS-PS1-2. Analyze and interpret data on the properties of substances before and after the substances interact to determine if a chemical reaction has occurred.
HS-PS1-2. Construct and revise an explanation for the outcome of a simple chemical reaction based on the outermost electron states of atoms, trends in the periodic table, and knowledge of the patterns of chemical properties.
