Given below are two statements:
Statement I: In redox titration, the indicators used are sensitive to change in pH of the solution.
Statement II: In acid-base titration, the indicators used are sensitive to change in oxidation potential.
In the light of the above statements, choose the most appropriate answer from the options given below
Statement I: In redox titration, the indicators used are sensitive to change in pH of the solution.
Statement II: In acid-base titration, the indicators used are sensitive to change in oxidation potential.
In the light of the above statements, choose the most appropriate answer from the options given below
Show Hint
Understand the role of indicators in titrations. Acid-base indicators respond to pH changes, while redox indicators respond to oxidation potential changes
- Both Statement I and Statement II are correct
- Both Statement I and Statement II are incorrect
- Statement I is correct but Statement II is incorrect
- Statement I is incorrect but Statement II is correct
The Correct Option is B
Solution and Explanation
Statement I:
Redox titration indicators, such as starch or ferroin, are sensitive to changes in oxidation potential, not pH. Conclusion: Statement I is incorrect.
Statement II:
In acid-base titration, indicators like phenolphthalein and methyl orange respond to changes in pH, not oxidation potential. Conclusion: Statement II is also incorrect.
Since both Statement I and Statement II are incorrect, the correct answer is option (2).
