I can define oxidation and reduction operationally
and theoretically.
I can define oxidizing agent, reducing agent,
oxidation number, half-reaction, and
disproportionation.
I can differentiate between redox reactions and
other reactions, using half-reactions and/or
oxidation numbers.
I can identify electron transfer, oxidization agents
and reducing agents in redox reactions that occur
in every day life, in both living systems and non
living systems i.e. corrosion
I can compare relative strengths of oxidization and
reducing agents, using empirical results.
I can predict the spontaneity of a redox reaction,
based on standard reduction potentials, and
compare their predictions to experimental results.
I can write and balance equations for redox
reactions in acidic and neutral solutions by –using
half-reaction equations obtained from a standard
reduction potential table – developing simple halfreaction equations from information provided
about redox changes – assigning oxidation
numbers, where appropriate, to the species
undergoing chemical change.
I can perform calculations to determine quantities
of substances involved in redox titrations.
I can define, anode, cathode, anion, cation, salt
bridge/porous cup, electrolyte, external circuit,
power supply, voltage cell and electrolyte cell.
I can identify the similarities and differences
between the operation of a voltaic cell and that of
an electrolytic cell.
I can predict and write the half-reaction equation
that occurs at each electrode in an
electrochemical cell.
I can recognize that predicted reactions do not
always occur.
I can explain that the values of standard reduction
potential are all relative to 0 volts, as set for the
hydrogen electrode at standard conditions.
I can calculate the standard cell potential for
electrochemical cells.
I can predict the spontaneity or non spontaneity of
redox reactions based on standard cell potential,
and the relative positions of half-reaction
equations on a standard potential table.
I can calculate mass, amounts, current and time in
single voltaic and electrolytic cells by applying
Faraday’s law and stoichiometry.
