Testing Gases!
The hydrogen “pop” test
Part 1: Using https://chemix.org/ create a picture of the
equipment set up for this experiment, Remember to annotate
(label all the equipment). Insert the completed picture here:
Part 2: Please answer the questions below:
1.Is this a chemical reaction? What evidence do you have of
this?
2.How did you know that hydrogen gas was being produced?
3.What was the appearance of this gas?
4. When testing for hydrogen, why does the match need to be
placed in the mouth of the test tube as soon
as the rubber stopper is removed?
5. Besides the hydrogen gas, another compound was produced
in this reaction. Name the two elements that you think would
make up this compound and try writing the name of this
compound.
6. Write a word equation and chemical equation for the reaction
taking place
7. Did you hear a ‘pop’ in step 3 of the experiment
both times? If no sound was produced, suggest an explanation
for this.
8. What was the danger of using
Hydrogen gas in the Hindenburg?
Which gas would be a better
alternative and why?
