answered-by-expert Expert Answer

Potassium permanganate is a very useful salt, but should be handled with care as its pure form is toxic to humans.

Disadvantages

· It has harmful effect on environment.

· Potassium permanganate is toxic and irritating to skin and mucous membranes.

· No byproducts are generated when preparing the feed solution, however this dark purple/black crystalline solid can cause serious eye injury, is a skin and inhalation irritant, and can be fatal if swallowed. Over-dosing is dangerous and may cause health problems such as chemical jaundice and drop in blood pressure.
