New syllabus, high-quality notes used as teaching and study material for HSC Chemistry students. These notes have been used to help students score 90+ in their HSC exams in 2019.
Please note that the order of these notes do not completely align with what's outlined by NESA's syllabus. The syllabus content has been rearranged to create a more logical and cohesive learning experience for students. These notes contain content from Module 5: Equilibrium and Acid Reactions as many school teachers do not teach this section until Term 2 Year 12.
The notes are divided into 5 sections:
Section 1: Properties of Acids and Bases
In this section, students are formally introduced to acids and bases for the first time. The section begins with models of acids and bases, followed by reactions involving acids and bases.
Section 2: Using Bronsted-Lowry Theory
This section explores the use of Bronsted-Lowry theory of acids and bases in more detail including concepts such as strength and concentration of acids/bases, pH, pOH and self-ionisation of water.
Section 3: Weak Acid and Base Dissociation
Section 3 comprises of content from Module 5: Acid Dissociation and part of Module 6: Quantitative Analysis. In this section, students will learn about the concept of Ka and pKa in both strong and weak acids as well as calculation questions involving them.
Section 4: Buffers
Students will learn about how weak acids and bases can cooperately function to form buffer systems. In addition, the concept of acidic and basic salts will also be introduced in this section.
Section 5: Quantitative Analysis - Titration
This is the final and largest section of Module 6. Section 5 focuses on titration as a volumetric analysis technique in which students will be required to apply all knowledge learnt from section 1 to 4. This section includes everything students are required to know regarding titration including practical techniques, titration curves, indicators and calculation questions. Conductometric titration will also be explored in this section.
