In
connection with the topic "ACIDS, BASES and SALTS" students of grade
X practiced a lab activity about the pH indicator.
After
explanation of the pH concept, the students were given three unknown liquids
and were asked to identify the solutions using a universal indicator.
The
students tested the solutions by adding the universal indicator, observed the color
change and have come out inferring the nature of the solution given.
