Potassium Permanganate is used for purifying drinking water, because
|
|
it is a sterilising agent
|
|
|
it dissolves the impurities of water
|
|
|
it is a reducing agent
|
|
|

|
Explanation:
Detailed explanation-1: -Potassium permanganate (KMnO4) is a strong oxidising agent. It oxidises the impurities in water and hence it is used for purifying drinking water.
Detailed explanation-2: -Potassium permanganate, KMnO4, is a powerful oxidizing agent, and has many uses in organic chemistry.
Detailed explanation-3: -Ozone(O3) which is the most powerful oxidant used for water purifications. The removal of unwanted taste and smell/odour can be treated by ozone oxidant. Metals like magnesium, sulphur and iron are oxidized by the ozone and convert into soluble particles.
