Preparing and Testing Hydrogen Gas: A Microscale Approach—ChemTopic™ Lab Activity

Hydrogen is the most abundant element in the universe and the second most abundant in living things. Despite this, very little hydrogen is found on Earth as a gas because it is easily oxidized and combines readily with many other elements. With the Preparing and Testing Hydrogen Gas: A Microscale Approach—ChemTopic™ Lab Activity, generate hydrogen gas by reacting zinc metal with hydrochloric acid, collect it by water displacement and study its properties.
