redox Flashcards
1
Q
oxidation
A
oxidation number of an let increases and e- and H+ are released
2
Q
reduction
A
the oxidation number of an elt decreases and e- and H+ are consumed
3
Q
oxidant
A
the elt that accepts e- and is reduced in a reaction
4
Q
reductant
A
the elt releases e- and is oxidized in a reaction
5
Q
pe
A
measure of the oxidation-reduction capacity of a natural water
high pe : oxidizing conditions
low pe : reducing conditions
an oxidant with higher pe can oxidize reductant with lower pe
