Question
KMNO4 ACT AS ______________ IN TIRATION.
a. Self indicator
b. Internal indicator
c. pH indicator
d. External indicator
Solution
KMNO4 acts as a Self Indicator in titration.
Here's why:
In a titration process, an indicator is used to determine the endpoint of the reaction. A self-indicator is a substance that changes its color when the reaction is complete.
Potassium permanganate (KMnO4) is a strong oxidizing agent and it has a deep purple color in solution. When it reacts with the substance to be titrated, it gets reduced and the purple color disappears.
So, when the purple color of KMnO4 disappears, it indicates that the reaction is complete. Hence, KMnO4 acts as a self-indicator in a titration process.
