6.3 Flashcards
A chemical species with a strong tendency to be reduced
strong oxidizing agent
A chemical species with a strong tendency to be oxidized
strong reducing agent
Metals with more than one charge do what
oxidize and reduce
Prefer to be oxidized means
prefer to lose electrons
Prefer to be reduced means
prefer to gain electrons
What are the two rules for a redox process to be spontaneous
- one species is reduced and one is oxidized
2. The one being reduced is higher up on the left-hand side
If two species are on the same side of the Table of Reduction:
no reaction occurs
If two species are on different sides of the Table of reduction
a reaction will occur
What is the rule if there are multiple possible reactants
according to the Table, the species with the highest tendency to oxidize/reduce will do it
What process do you follow when determining which reactants will participate in the redox reaction
- determine which oxidize and which reduce
- determine whch are more powerful
- balance
Which half-reaction is above which
the reduction one (the one that gains electrons) is on top
If the balanced equation requires H+ but H+ is not listed as a reactant
the reaction is not spontaneous
