Question

Which oxidant is used for the purification of drinking water?

Answer 1

Oxidant

• During a redox reaction, an oxidant is a reactant that oxidizes or removes electrons from other reactants.
• An oxidant is sometimes referred to as an oxidizer or an oxidizing agent.
• An oxygenation reagent or oxygen-atom transfer agent is used when the oxidant contains oxygen.

Purification of drinking water

• One of the most prevalent methods for purifying heavy metal-contaminated water is oxidation.
• The most powerful oxidant used in water cleaning is ozone $\left({\mathrm{O}}_3\right)$.
• Ozone oxidants can be used to remove unpleasant tastes and odors.
• Ozone oxidizes metals, including magnesium, sulfur, and iron, turning them into soluble particles.
• Another method of purifying is the use of bleaching powdered chlorine.
• Chlorine $\left({\mathrm{Cl}}_2\right)$ gas can be directly injected into the water and purified.
