What is the indicator used in Argentometric titrations?
Show Hint
Argentometric titrations: Eosin dye (adsorption indicator).
Updated On: Jun 5, 2025
- Starch solution
- Eosin dye
- KMnO$_4$ solution
- Phenolphthalein

Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Argentometric titrations involve the determination of silver ions (Ag$^+$). Eosin dye is commonly used as an adsorption indicator in these titrations, particularly for halide determination (like chloride, bromide, and iodide). The dye adsorbs onto the precipitate at the equivalence point, causing a color change.
