EXPERIMENT 7 Measuring pH
pH Color Scale
You can read the pH
value of the solution
by the color of the
indicator paper. It
extends from red
(acidic) through
yellowish green
(neutral) to blue
(basic).
Explanation:
You can use the pH indicator paper to determine the degree of
acidity of a liquid. Acidic liquids are red, neutral ones (meaning that
they are neither acidic nor basic) are yellowish green, and basic
liquids, which are the opposites of acids, are blue.
More Tests!
Determine the pH value
of other liquids!
Tip: Put unused indicator paper
back in the bag, because it can
become discolored by water
particles in the air.
