As dilute sulfuric acid is ideal for redox titration because it is neither an oxidizing agent and nor a reducing agent. On the other hand, KMnO₄ which is the indicator, oxidises HCl to Cl₂ as HCl is a mild reducing agent_. Due to which, the purpose of the experiment is not served. So, dilute sulphuric acid is used.
