Description

Experiment C1.2.1.1 demonstrates that in a chemical reaction the total mass of the substances involved in the reaction remains unchanged. In the experiment, hydrochloric acid is pipetted into a test tube. Pieces of marble are introduced into a balloon. The reaction is started by tipping the pieces of marble into the acid. Although bubbles form, it can be observed that no mass is lost.
