Question: What is the role of a pH indicator in a titration?
Options:
To increase the reaction rate
To provide a color change at the endpoint
To stabilize the solution
To dilute the reactants
Correct Answer: To provide a color change at the endpoint
Solution:
A pH indicator changes color at a specific pH range, signaling the endpoint of the titration.

Questions & Step-by-Step Solutions
What is the role of a pH indicator in a titration?
Step 1: Understand that a titration is a process where one solution is added to another to find out how much of one is needed to react with the other.
Step 2: Know that a pH indicator is a special chemical that changes color depending on the acidity or basicity of a solution.
Step 3: Realize that during a titration, the pH of the solution changes as you add the second solution.
Step 4: Learn that the pH indicator will change color at a specific pH level, which tells you when the reaction is complete.
Step 5: Conclude that the color change of the pH indicator signals the endpoint of the titration, helping you know when to stop adding the second solution.
