WebDec 12, 2024 · If the colour stays after 30 seconds, then end point is reached. If the colour disappears before 30 seconds, then the titration is not finished, so more $\ce{KMnO4}$ should be added. As far as I understand, at the end point, all the reducing agent is depleted. So, the colour of $\ce{KMnO4}$ stays. WebDec 16, 2024 · Theory: The aqueous solution of KMnO4 needs to be standardized using sodium oxalate.
