Calculate the solubility of PbSO4 whose Ksp = 2.0 x 10-14:
2
Oxidation Reduction Reactions (REDOX)
3
Chemical reactions in which electrons are transferred
REDOX Reactions Chemical reactions in which electrons are transferred
4
Oxidation The act of losing electrons Oxidation number increases
5
Reduction The act of gaining electrons Oxidation number decreases
6
REDOX Fact You cannot have oxidation without reduction or reduction without oxidation
7
Oxidizing Agent A substance that oxidizes another
The oxidizing agent will be reduced
8
Reducing Agent A substance that reduces another
The reducing agent will be oxidized
9
Balancing REDOX Reactions
10
Balancing Redox Rxns Determine all ox #
Determine elements being oxidized & reduced Divide rxn into half-rxns Balance half-rxns
11
Balancing Half-Rxns Balance redox elements Balance ox # with e-
Balance e- between the two half-rxns
12
Balancing Half-Rxns Balance total charge with H+ or OH-
Balance H’s with water Check balance with oxygen
13
Balancing Redox Rxns 5) Add the two half-reactions
Cancel like substances from each side of the full reaction Check work
