Question
Write down use of KMnO4
✓
Answer
→ Potassium permanganate is used as a favourite oxidant in preparative organic chemistry.
→ Its uses are for the bleaching of wool, cotton, silk and other textile fibres and for the decolourisation of oils are also dependent on its strong oxidising power.
→ An aqueous solution of potassium permanganate is used for gargling to keep mouth germfree as it is antiseptic.
→ It is useful as titrant in redox titrations to know the proportion of metal ions like iron (II) and organic compounds like oxalic acid.
