At what pH range should the titration be performed and why?
At what pH range should the titration be performed and why?
- pH 7 to maintain neutrality
- pH > 9 to prevent precipitation of AgOH and Ag2O (correct)
- pH < 6.5 to prevent formation of soluble salts with Ag+
- pH 10 to enhance the color change at the endpoint
