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.
