Enlist uses of hydrogen peroxide.
✓

Answer

  • Hydrogen peroxide is used as mouthwash, germicide and mild antiseptic.
  • It is used as a preservative for milk and wine.
  • It is used as a bleaching agent for soft materials, due to its mild oxidising property.
  • Due to its reducing property, is used as an antichlor to remove excess chlorine from fabrics which have been bleached by chlorine.
  • Nowadays it is used in environmental chemistry for pollution control and restoration of aerobic condition of sewage water.
