Areas of study
Outcome 1
On completion of this unit the student should be able to evaluate the suitability of techniques
and instruments used in chemical analyses.
Key knowledge
volumetric analysis including determination of excess and limiting reagents and titration
curves: simple and back titrations, acid-base and redox titrations
gravimetric analysis
calculations including amount of solids, liquids and gases; concentration; volume,
pressure and temperature of gases
the writing of balanced chemical equations, including the use of oxidation numbers to
write redox equations, and the application of chemical equations to volumetric and
gravimetric analyses
principles and applications of chromatographic techniques (excluding features of
instrumentation and operation), and interpretation of qualitative and quantitative data
from:
– thin layer chromatography (TLC), including calculation of Rf
– high performance liquid chromatography (HPLC) and gas chromatography (GC)
including Rt and the use of a calibration graph to determine amount of analyte
principles and applications of spectroscopic techniques (excluding features of
instrumentation and operation), and interpretation of qualitative and quantitative data
from:
– atomic absorption spectroscopy (AAS) including electron transitions and use of
calibration graph to determine amount of analyte
– infrared spectroscopy (IR) including use of characteristic absorption bands to
identify bonds
– proton and carbon-13 nuclear magnetic resonance spectroscopy (NMR) including
spin, the application of carbon-13 to determine number of equivalent carbon
environments; and application of proton NMR to determine structure: chemical
shift, areas under peak and peak splitting patterns (excluding coupling constants),
and application of n+1 rule to simple compounds
– visible and ultraviolet spectroscopy (visible-UV) including electron transitions
and use of calibration graph to determine amount of analyte
– mass spectroscopy including determination of molecular ion peak and relative
molecular mass, and identification of simple fragments
matching analytical technique/s to a particular task: single and combined techniques.
Outcome 2
On completion of this unit the student should be able to identify and explain the role of
functional groups in organic reactions and construct reaction pathways using organic molecules.
Key knowledge
Structure including molecular, structural and semi-structural formulae, and International Union
of Pure and Applied Chemistry (IUPAC) nomenclature of alkanes, alkenes, amines,
haloalkanes, alkanols (CnH2n+1OH), alkanoic acids (CnH2n+1COOH) and esters up to C10
common reactions of organic compounds including equations: addition reactions of
alkenes (addition of hydrogen halides and water limited to symmetrical alkenes),
substitution reactions of alkanes and primary haloalkanes, oxidation of primary alkanols,
and esterification
Chemistry Unit 3 Introduction Page 3
chemical bonding:
– primary, secondary and tertiary structures of proteins
– the role of the tertiary structure of proteins in enzyme action
– denaturing of proteins: effect of changes in pH and temperature on bonding
– primary and secondary structure of DNA
organic reaction pathways including appropriate equations and reagents:
– production of esters from alkenes
– condensation reactions that produce lipids (limited to triglycerides)
– condensation and polymerisation reactions that produce large biomolecules
including carbohydrates, proteins and DNA
– production of biochemical fuels including the fermentation of sugars to produce
ethanol
– function of organic molecules in the design and synthesis of medicines including
the production of aspirin from salicylic acid.
How to use this book There are eight weeks in this book covering Area of
Study One, Chemical Analysis.
Each week you should:
1. Read the notes, do the “Quick check” questions and
correct your answers as you go.
2. Do any practical work required, or arrange for a time
and place when the practical work will be done.
3. Complete the SEND exercises in the assignment
booklet and send them in.
Websites and Heinemann eChemistry 2 CD
There are also some excellent interactive activities as well as risk and
safety phrases used in the material safety data sheet (MSDS) on the
Heinemann eChemistry2 CD that came with your textbook. You are
urged to refer to these activities when you see the textbook CD icon on
the left.

Practical Work Practical work is an extremely important part of your Year 12
Chemistry studies. This is a compulsory part of the course and
is best carried out under supervision in a school laboratory.
In Unit 3, the first school assessed coursework task, SAC 1,
requires you to submit an Extended Experimental Investigation
(EEI) relating to the detailed study “Chemical analysis” and SAC
2 in study area 2.
To complete this by distance mode you must choose one of the
following:
The practical work that requires lab access can be conducted
* If you are school-based and your school has the
appropriate equipment and expertise (eg appropriate
teacher and/or lab. technician) then the EEI can be
done at your school OR
* At the DECV in Thornbury, A lab day will be
held on 20 March 2015 in Term 1. Your teacher
will send you details about the date a few weeks
before hand.
Safety First! Some chemicals used are poisonous. Use minimum
quantities and avoid skin contact with all chemicals. Pour
carefully to avoid inhaling fumes, particularly if fume
cupboards are required. Use bench mats when heating, and
be careful with hot liquids. Laboratories should have fire
extinguishers and fire blankets on hand.
How much time do
you need to
spend?
This unit requires an average of 100 hours of study, or
approximately 6 to 7 hours a week. For students aiming for
a high Chemistry study score eight to ten hours a week would
be a more realistic target. Unit 3 is 16 weeks in length.
However, these figures do depend on your prior knowledge
and aptitude for the subject. You may find it helpful to allocate
a specific time of day and week to do your Chemistry work, so
a work schedule or timetable would be a good idea as it is
crucial to keep up to date with the work load.
Chemistry Unit 3 Introduction Page 5
Assessment The award of satisfactory completion (S) for Unit 3 is based on the
student completing all of the weekly submissions satisfactorily.
The student‟s level of achievement in Unit 3 will be determined by
school-assessed coursework and the end of year exam.
School Assessed Coursework (SAC)
School-assessed coursework for Unit 3 will contribute 20% to the study
score for the year and 60% of the End of Year exam. The SACs that you
will do at DECV are shown below and will be marked by your teacher.
The posting and deadline dates for these SACs are shown below.
SAC Outcome Marks allocated Assessment Task
SAC 1 Outcome 1 50 An extended
experimental
investigation
SAC 2 Outcome 2 25 A written report of
one practical activity.
SAC 3 Outcome 2 25 A response to a
stimulus material
Total Marks 100
End of-year Written Examination
You will complete an examination, which consists of a set of questions
designed to assess your understanding of all Areas of studies in Unit 3
and Unit 4.
Duration of exam: Two and a half hours
The examination will contribute 60 per cent to the study score.
SAC –Time table
It is your responsibility as a VCE student at the DECV to ensure that
work is submitted on time. You will find a timetable for Weeks 1-8 of
Unit 3 on page 10.
The SAC Timetable is printed on the next page. You cannot have
unlimited time to complete these. If they are not received by the date
indicated as the deadline they will not receive a grade and the reasons for
this will be indicated in your report. The only exception will be if you
provide suitable documentation such as a medical certificate or a letter
from a parent, school Principal or VCE Coordinator. If you have any
questions regarding this matter please contact your teacher.
