Metals in Hydrochloric Acid

In this interactive activity adapted from Iowa State University, observe the chemical reaction that occurs when different metals are dipped in a solution of hydrochloric acid. Hydrochloric acid dissolves some metals to form oxidized metal chlorides and hydrogen gas, the latter of which is visible in the animation as bubbles floating to the surface. Depending on their atomic structure and how readily they give up electrons when exposed to hydrogen ions in an acidic solution, certain metals, including zinc and magnesium, corrode more easily than others.

This media asset was adapted from Iowa State University: Reactions of Metals and Metal Ions Experiment.
