Let us get some basic stuff together and make a hydrogen balloon to demonstrate in the class. The main idea is to collect hydrogen gas from an acid-metal reaction and show the students the safest way to do it.

One of the most challenging tasks of a science teacher in a chemistry class is how to show that gases exist and it can be collected from simple reactions. Most common amongst these gases are OXYGEN, HYDROGEN, and CARBON DIOXIDE.
Yet there is a simple activity that could be done as a demo or class experiment to confirm those scientific explanation about acid-metal reaction. Be sure the materials are readily available in your laboratory. There are other processes to produce these gases but these are the ones helpful and practical in a school setting. (more…)
