Year 12 Chemistry Revision Notes Module 2

In general, this document (14 pages. created in 2012) provides content, analysis and examples behind the course dot points as
outlined in the Board of Studies chemistry syllabus. By breaking down the three core modules
(production of materials, the acidic environment, chemical monitoring and management) into their
subtopics and concepts, and structuring these notes accordingly, the relevant information is provided
in a clear and concise form. With the inclusion of useful diagrams and important molecular formula
presented in a visual manner, the notes should be easily accessible by all students of varying
abilities.
Year 12 students taking chemistry for the HSC would find this exam preparation material useful as a
comprehensive summary of the fundamentals behind what should be known and learnt for the final
exam. This document can be used as a learning aid, to clarify or even enhance the student’s
knowledge regarding the relevant course content. The notes can also serve as a quick and easy
point of reference when revising for the exam or explaining a particular topic/concept.
NB: This document contains only module 2 for someone preparing for the HSC Chemistry exam,
Modules 1 and 3 are separate downloads.

Crucial Information to Maximise Performance
MODULE 2 – THE ACIDIC ENVIRONMENT
1. Indicators were identified with the observation that the colour of some flowers depends on soil
composition
2. While we usually think of the air around us as neutral, the atmosphere naturally contains acidic
oxides of carbon, nitrogen and sulphur. The concentrations of these acidic oxides have been
increasing since the Industrial Revolution
3. Acids occur in many foods, drinks and even within our stomachs
4. Because of the prevalence and importance of acids, they have been used and studied for
hundreds of years. Over time, the definitions of acid and base have been refined
5. Esterification is a naturally occurring process which can be performed in the laboratory
