Dear parents and students.
I hope you had a great summer break.
This is Mr. Koc Secondary science (Chemistry) teacher. I
will be teaching G9-12 IGCSE and IB Chemistry.
Starting from the beginning of this new academic year I will
be teaching Redox processes as the first
unit of the year.
Students will start getting essential idea Redox
(reduction–oxidation) reactions play a key role in many chemical and
biochemical processes.
They will learn about;
·
Oxidation and reduction can be considered in
terms of oxygen gain/hydrogen loss, electron transfer or change in oxidation
number.
·
An oxidizing agent is reduced and a reducing
agent is oxidized.
·
Variable oxidation numbers exist for transition
metals and for most main-group non-metals.
·
The activity series ranks metals according to
the ease with which they undergo oxidation.
·
Electrochemical cells
·
Voltaic cells convert energy from spontaneous,
exothermic chemical processes to electrical energy.
·
Oxidation occurs at the anode (negative
electrode) and reduction occurs at the cathode (positive electrode) in a
voltaic cell.
·
Electrolytic cells convert electrical energy to
chemical energy, by bringing about non-spontaneous processes.
·
Oxidation occurs at the anode (positive
electrode) and reduction occurs at the cathode (negative electrode) in an
electrolytic cell.
I wish you and our students to have a wonderful, fruitful
and enjoyable new academic year with full of education.
