PREDICTING REDOX REACTIONS KEY TERMS AND CONCEPTS
CONCEPTS
Students will know:
· A relative ranking of the strength of oxidizing and reducing agents has been developed from empirical evidence.
· Redox tables list the strongest oxidizing agent in the top left corner of the table and the strongest reducing agent in the bottom right corner of the table.
· Redox tables can be used to predict whether a redox reaction occurs spontaneously.
· A relative ranking of the strength of oxidizing and reducing agents has been developed from empirical evidence.
· Redox tables list the strongest oxidizing agent in the top left corner of the table and the strongest reducing agent in the bottom right corner of the table.
· Redox tables can be used to predict whether a redox reaction occurs spontaneously.
KEY TERMS
Redox Table:
A table listing standard reduction potentials of common oxidizing agents and reducing agents in order from strongest to weakest. Also known as a standard potential table.
Reducing Agent:
A substance that loses or gives up electrons to another substance in a redox reaction.
Oxidizing Agent:
A substance that gains or removes electrons from another substance in a redox reaction.
Redox Spontaneity Rule:
A spontaneous redox reaction occurs only if the oxidizing agent (OA) is above the reducing agent (RA) in a table of relative strenthgs of oxidizing and reducing agents.
Cation:
A positively charged ion, i.e., one that would be attracted to the cathode in electrolysis.
Anion:
A negatively charged ion, i.e., one that would be attracted to the anode in electrolysis.
