WHAT’S HAPPENING?
Out of foam
YOU WILL NEED
→ test tube
→ stopper
→ soap solution
→ cup of flat mineral water
HERE’S HOW
1. Pour 2 cm of soap solution (from
Experiment 13) into a test tube, insert
the stopper, and shake until you get
some foam.
2. Pour some mineral water into a yogurt
container and add double the quantity
of mineral water to the foam solution.
Does the foam hold up?
The column of foam collapses, and
you will find a crumbly substance on
the surface of the liquid. That’s lime
soap. So mineral water contains
minerals, as the name implies. It
contains soluble calcium hydrogen
carbonate, among other things.
