In the titration of mohr salt against \(\mathrm{KMnO}_{4}\), the indicator used is
- A diphenyl amine
- B \(\mathrm{KMnO}_{4}\)
- C phenolphthalein
- D methyl orange
Answer & Solution
Correct Answer
(B) \(\mathrm{KMnO}_{4}\)
Step-by-step Solution
Detailed explanation
In the titration of Mohr's salt with \(\mathrm{KMnO}_{4}\), the indicator used is \(\mathrm{KMnO}_{4}\) itself. Because \(\mathrm{KMnO}_{4}\) is very intense purple in colour. When, the solution changes to pink, end point is noted.…
