redox

1. . []

A contraction of reduction-oxidation, a type of chemical reaction in which one reactant is reduced (gains electrons) while the other is oxidized (loses electrons). Examples of redox mud chemistry are

  • sulfite anions to remove molecular oxygen
  • sulfide removal by oxygen or peroxide
  • air oxidation of lignite to create more humic acid
  • sulfate reducing bacteria that generate sulfide ions by biological redox reactions
  • chromate ions being converted to chromic ion in a mud system.
