Redox Equilibria

Question 1

define the terms standard
electrode potential and
standard cell potential;

Question 2

describe the standard
hydrogen electrode;

Include labelled diagram of
standard hydrogen
electrode.

Question 3

describe methods used to
measure the standard
electrode potentials of:

(a) metals or non-
metals in contact with
their ions in
aqueous solutions;
and,

(b) ions of the same
element in different
oxidation states;

Question 4

use standard electrode
potentials of cells:
(a)
(b)
to determine the
direction of electron
flow; and,
to determine the
feasibility
reaction;

Question 5

predict how the value of an
electrode potential varies
with concentration; and,

Question 6

apply the principles of
redox processes to energy
storage devices. Include references to two of the
following batteries:
Leclanche’ dry cell, lead acid
accumulators
(secondary
cells); and fuel cells.
