This beaker contains a dilute solution of hydrochloric acid, HCl.
A few magnesium turnings are added to the acid.
The magnesium reacts rapidly with the acid to produce bubbles of hydrogen gas, H2, and magnesium salts.

Let's see how the strength of the acid affects the rate of this reaction by collecting the hydrogen formed in a balloon.
