Oxidation Reduction Fundamentals of Electrochemistry
Oxidation number
In a simple substance, the oxidation number of an element = 0
In a compound, the algebraic sum of the oxidation numbers of each element = 0
Redox reactions
trim
oxidation number balancing method
Ion-electron balance method
Element potential diagram 146
E right > E left, the substance undergoes a disproportionation reaction under standard conditions
Chemical Power 148
thermodynamics
and free energy G
rG=-nFE pool
Faraday's constant F=9.65*1000J/V*mol
Equilibrium constant
lnK=nFE/RT

Factors affecting electrode potential
concentration
When the concentration of oxidized substances decreases, the electrode potential of the electric pair decreases, and vice versa.
Concentration difference battery
Same electric pair, different electrode potentials
