Chapter 11- Oxidation- Reduction Reactions Flashcards
1
Q
What has an oxidation number of 0?
A
Free elements (ex. N2, P4, S8, and He)
2
Q
Catalase
A
Biological enzyme used to protect cells from excessive oxidation by free radicals or reactive oxygen species
3
Q
Typical Oxidation number of oxygen
A
-2
4
Q
Disproportionation reaction
A
A species is simultaneously oxidized and reduced to form two different products
5
Q
Potentiometry
A
Oxidation-reduction titration using a voltmeter to measure emf which is analogous to performing an acid-base titration with a pH meter.
