Section 1

Question Answer
Oxidationdefined as a loss of electrons to give a higher oxidation state (more positive).
Reductiondefined as a gain of electrons to give a lower oxidation state (more negative)
Reduction-oxidation (“Redox”) reaction one that occurs between a reducing and an oxidizing agent:
oxidizing agent (oxidant)tend to take on an electron or electrons and be reduced to a lower oxidation state:
reducing agent (reductant)tend to give up an electron or electrons and be oxidized:
reduction potential. reducing or oxidizing tendency of a substance will depend on
standard electrode potentialmeasures the tendency for a reduction process to occur at an electrode.
intensive propertiespotential increases as the tendency for reduction
standard hydrogen electrodeset at exactly 0 V.
the stronger an oxidizing agent the oxidized form is and the weaker a reducing agent the reduced form is. the more positive the electrode potential,
a positive value for its standard reduction potentiala greater tendency to occur than does the reduction of H+
