Purpose: You will demonstrate the use of indicators to determine the pH of a solution.
Variables:
Manipulated Variable: Type of solution.
Responding Variable: indicator
Controlled Variables:
Observations: see other side
Analysis: For each unknown solution, A, B & C, determine the range of its pH and explain how you used the
indicators to determine the pH range for each unknown solution.
