Chemistry IBDP is one of the six group 4 Sciences of the IB curriculum. The IBDP Chemistry program explores the three important aspects of chemistry: Physical, Organic, and Inorganic chemistry. The program requires the student to take a look at the qualitative and quantitative aspects of each of the sections using a range of techniques.

These techniques range from informative theoretical knowledge to practical applications in the lab and the real world. This holistic approach allows students to learn in a variety of methods including but not limited to exploration, discovery, gathering and interpreting data, analysing outcomes, and giving feedback. The IBO’s special attention to criteria ensures that the student can interconnect the subjects they have chosen and be able to apply them in real life.

In this chapter of IBDP Chemistry, we take an in-depth look at the concept of Redox reactions and related processes. The chapter can be divided into two sections, both of which are covered in a comprehensive manner in our notes. We begin with introducing reduction and oxidation and defining them followed by elaborating the concept of oxidation states and how half-equations may be effectively used for redox reactions.

We then take a look at oxidising and reducing agents and their classifications and characteristics to help us understand redox processes occurring in the environment around us. The second section takes a look the two types of electrochemical cells, voltaic and electrolytic, discussing their general characteristics, the processes that occur within them and their differences. We also explore how redox reactions occur within theses systems and can be represented clearly in theory.

We also discuss the factors that affect the electrochemical cells and the outcomes of varying them. We further define electrochemical cells using quantitative methods and calculations while discussing electrode potentials and related equations. These ideas are discussed with clarity using examples and finally, we explore the relationship between the Electrode potential of a cell and the spontaneity of the reaction.

At the end of this chapter, we can expect the students to have an understanding of Redox processes and their applications in both natural and man-made settings.
