Abstract : The reaction is complete between 60 and 90 degrees Celsius.
KMnO4 is a potent oxidizer in acidic environments. Under suitable storage conditions, it can hold its concentration for an extended period. In addition to being a self-indicator, its small excess provides the solution a distinctive pink colour.
HCl cannot be substituted for H2SO4 due to its rapid oxidation to chlorine in the presence of permanganate. Nitric acid is stronger than KMnO4.
