"Nothing in life is to be feared, it is only to be understood. Now is the time to understand more, so that we may fear less."

HSC chemistry tutoring at SIGI Learners is based on the current HSC chemistry syllabus, which contains 4 core modules:
Equilibrium and Acid Reactions
Students investigate the effects of changes in temperature, concentration of chemicals and pressure on equilibrium systems, and consider that these can be predicted by applying Le Chatelier’s principle. Students make reliable predictions by comparing equilibrium calculations and equilibrium constants to determine whether a combination of two solutions will result in the formation of a precipitate.
Students analyse how and why the definitions of both an acid and a base have changed over time, and how the current definitions characterise the many chemical reactions of acids. The chemistry of acids and bases contributes to industrial contexts and the environment. By investigating the qualitative and quantitative properties of acids and bases, students learn to appreciate the importance of factors such as pH and indicators.
Students examine the principles and applications of chemical synthesis in the field of organic chemistry. Current and future applications of chemistry include techniques to synthesise new substances – including pharmaceuticals, fuels and polymers. Students investigate the many classes of organic compounds and their characteristic chemical reactions.
Equilibrium & Acid Reactions Applying Chemical Ideas
Students investigate a range of methods used to identify and measure quantities of chemicals. They process and analyse data involving the identification and quantification of ions present in aqueous solutions. Students deduce or confirm the structure and identity of organic compounds by interpreting data from qualitative tests of chemical reactivity and determining structural information using proton and carbon‑13 nuclear magnetic resonance (NMR) spectroscopy.
HOW TO APPROACH
Rather than rote learn a series of chemical theories and ideas, which is not the essence of HSC Chemistry, it is much more beneficial for students to be able to relate their learning to everyday experiences and current issues which have a direct impact in their lives.
For instance, did you know that the sodium chloride (that is common table salt) can be used to extinguish fires?
- History of Chemistry
- Nature and Practice
- Application and Uses
- Implications to Society and the Environment
- Current Issues, Research and Development
How to Study
- Break it up
Try to categorise each module into smaller sections. Chemistry in Focus breaks the content up into manageable bits by integrating exercise questions designed to reinforce newly-learnt concepts and theories.
- Get on top of things
Organise and plan everything ahead of schedule and leave plenty of leeway for mishaps. Have a rough plan with all the important dates, and then fill in the finer details throughout the year depending on the situation.
- Always ask
Be proactive in your learning. One of the most effective methods is a study group. Team up with your friends and form a regular study group, take turns summarising notes, making up and answering questions, peer teaching, etc.
Excelling in Chemistry requires a 4 step process – reading, understanding, memorising and applying.
