MOM’s Acid-Base Chemistry
Introduction In this experiment, students react milk of magnesia with vinegar to study acid-base chemistry, chemical equilibrium, solubility, and heat of neutralization. Milk of magnesia (MOM), which still finds wide use as a laxative and antacid, is a suspension of magnesium hydroxide in water. The suspended particles of magnesium hydroxide give MOM its characteristic milky-white […]
Introduce Environmental Studies with a River Tank™
Often the most important changes in an aquatic environment are chemical changes. A River Tank is a good model system for students to investigate changes in water chemistry. First, using the tank eliminates the need for parent/guardian permission and problems associated with a field trip to a stream. Second, the tank makes it easy to manipulate factors […]
