Molecular Geometry with Balloons
Background Molecular geometry can be tricky for students to grasp. Two-dimensional representations of molecular geometries predicted by the valence-shell electron-pair repulsion (VSEPR) model can be difficult to comprehend. Three-dimensional models, however, give students the opportunity to view and manipulate models as needed, making molecular geometry much easier to understand. In this activity, each balloon represents […]

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 […]
