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 Acids and Bases. The chapter can be divided into eight sections, all of which are covered in a comprehensive manner in our notes. We begin with the roles of acids and bases and how they may be defined by varying theories. We then discuss their properties and reactions with different types of compounds alongside introducing titration reactions. We then take a detailed look at the pH scale, the process of  calculating and measuring pH with greater accuracy and its application to water molecules.

We then discuss factors that affect the strength of acid and bases followed by looking at ways in which acid deposition affects the environment. The next section takes a closer look at Lewis’ theory of acids and bases by itself and in comparison with other theories. We follow this with a more quantitative approach of acids and bases and the different factors that affect it. Finally, we take  a look at buffer solutions, pH curves and analyze them in titration reactions to draw conclusions alongside indicators and how they may be effectively used.

At the end of this chapter, we can expect the students to have an in-depth understanding of Acids and Bases in both qualitative and quantitative terms.
