Chapter 9.1 Flashcards
Oxidation in terms of electrons
The loss of electrons
Reduction in terms of electrons
The gain of electrons
Oxidation in terms of hydrogen or oxygen
The loss of hydrogen or the gain of oxygen
Reduction in terms of hydrogen or oxygen
The gain of hydrogen or the loss of oxygen
Oxidation in terms of oxidation numbers
An increase in oxidation number
Reduction in terms of oxidation numbers
A decrease in oxidation number
Disproportionation reaction
A reaction in which the same species is oxidized and reduced
What is required for a reaction to be a redox reaction?
Oxidation number must change
Oxidizing agent
A substance that oxidizes other species and is reduced itself. They take electrons away from something
Reducing agent
A substance that reduces other species and is oxidized in the process. They give electrons to something
How are the metals in a reactivity series arranged?
Arranged from most easily oxidized to form a positive ion to least easily oxidized
Biochemical oxygen demand
The amount of oxygen used by aerobic microorganisms in water to decompose the organic matter in the water over a fixed period of time at a fixed temperature
