24. How did you identify the acidic samples in
your activity?
How did you identify the basic samples in
your activity?

25. What is the relationship between the result of
your activity and the video clip presented?
• Acids- substances whose waters solution
exhibits the following properties: turns litmus
paper red, has sour taste, neutralizes bases and
reacts with active metals and produce
hydrogen gas.
• Base- substances whose water solution
exhibits the following properties:
turns litmus paper blue, has bitter
tastes, has a soapy feeling and
neutralizes acids.

26. Are the answers of the groups:
MATHinik, MahuSCIENCE and MaARTi
are correct? How can you say so?
Indicator- a natural substance that is used
to determine the acidity and basicity of a
solution.
Neutral solution- has a pH level of 7.
pH- potential of hydrogen ion (H+),
measures the acidity or basicity of a
substance.
