This
experiment will show that atoms and molecules react together to form different
types of matter.
A
clean, transparent bottle
Vinegar
Baking soda
A funnel
A balloon
Experiment 1:
How to create a gas?
Pour
vinegar into the bottle
until it is one-third full.
Experiment:
Materials
required:
Using
the funnel, fill the balloon with baking soda.
When
the vinegar molecules (CH3COOH) come into contact with the baking
soda molecules (NaHCO3), a chemical reaction takes place. The reaction
generates several products, including large amounts of carbon dioxide gas (CO2).
The carbon dioxide inflates the balloon.
Lift
up the balloon so that the baking soda falls
into the vinegar.
Watch
what happens: white foam appears in the bottle and the balloon inflates.
Stretch
the opening of the balloon over the mouth of the bottle, being careful not to
spill any baking soda into the bottle.
What
happens?
