In the titration of mohr salt against KMnO ₄ , the indicator used is

Step-by-step solution

In the titration of Mohr's salt with KMnO ₄ , the indicator used is KMnO ₄ itself. Because KMnO ₄ is very intense purple in colour. When, the solution changes to pink, end point is noted. Dark purple MnO ₄⁻ Reduction with Mohr's salt Pink Mn ²⁺
