3. Course Details
Course Description2 (Handbook Entry)
This course teaches the essential methods in analytical chemistry applicable to chemists, biologists, and most other disciplines of science. The course covers data analysis methods of treating analytical data including estimation of uncertainties, chromatography and other separation techniques, the applications of spectroscopy (UV/Visible Absorption, infra red, fluorescence and mass spectrometry) to analysis and the basics of electrochemistry including pH measurements.
Course Aims3
The aim of this course is to introduce students to the physical and chemical basis of analytical techniques and to get them to be able to evaluate why certain methods might be better than others for a given situation.
Student Learning Outcomes4
At the end of this course you should be able to describe the physical and chemical principles underlying a range of analytical techniques, including solvent extractions, electrochemistry chromatography, mass spectrometry, atomic, molecular electronic, and infrared spectroscopies. Using this, the appropriate analytical technique for a given situation should be able to be determined. You should be able to interpret the data provided in terms of 'quality'.

Relationship to Other Courses within the Program
The course is an introduction to the area of analytical chemistry, building on the fundamental knowledge introduced in first year chemistry courses. It integrates with the other second year chemistry courses, and leads into the corresponding analytical course in Level 3.
4. Rationale and Strategies Underpinning the Course
Teaching Strategies
The development of a course which progressively builds on earlier material and links to material presented in the laboratory supports “Engaging” 1. Effective learning is supported when students are actively engaged in the learning process. 2. Effective learning is supported by a climate of inquiry where students feel appropriately challenged and activities are linked to research and scholarship.
Rationale for learning and teaching in this course6,
Ensuring that material presented in lectures relates to the laboratory material allows “Contextualising” 6. Students become more engaged in the learning process if they can see the relevance of their studies to professional, disciplinary and/or personal contexts. The course content has been tailored to allow “Dialogue” between the staff and the students. 7. If dialogue is encouraged between students and teachers and among students (in and out of class), thus creating a community of learners, student motivation and engagement can be increased. In addition, the course has been “Designed” to 10. Clearly articulated expectations, goals, learning outcomes, and course requirements increase student motivation and improve learning. 12. Graduate attributes - the qualities and skills the university hopes its students will develop as a result of their university studies — are most effectively acquired in a disciplinary context. “Group work in the laboratory groups supports 14. Learning cooperatively with peers — rather than in an individualistic or competitive way — may help students to develop interpersonal, professional, and cognitive skills to a higher level. Continual feedback through laboratory work allows for analysis and reflection 16. Meaningful and timely feedback to students improves learning.

Exam Period Final Marks
** To be awarded a pass in this subject, along with achieving a cumulative score of ! 50%, students must satisfy two conditions: (i) A mark of ! 60% in the continuous assessment component (laboratory, reports and data analysis), and (ii) Satisfactory overall performance (! 40%) in the examination component (data analysis test and final examination combined) Failure to satisfy both criteria could result in either a FL or UF (Unsatisfactory Fail) grade being awarded, or further assessment being offered at the sole discretion of the course coordinator. Students must ensure their availability to attend any supplementary examination that will usually be offered in the week before the commencement of semester 2; inability or failure to attend a supplementary examination may lead to a FL or UF (Unsatisfactory Fail) grade being confirmed.

Comments or Changes Resulting from Reviews
Major Course Review
2011
In order to reduce assessment time (for both staff and students) written reports have been phased out for all but one of the analytical labs. Marking of analytical results will be done in the laboratory. Exam reduced to 2 h. Data Analysis content assessed in a test in Week 6. Remainder of material assessed in final exam. Increase in value of laboratory component in assessment to reflect aims of course.
CATEI9
2011
Midsession test included to aid continuous assessment. The value of the practical component has been increased to aid continuous assessment.

10. Administration Matters
Expectations of Students
Workload Contact hours are 6 per week. The major out-of-class workload is associated with the laboratory program. Pre-laboratory work is expected to take 30-60 minutes per week and post-laboratory write-up is expected to take 1-3 hours per week.
Assignment Submissions
Laboratory reports should be submitted as described in the first laboratory class. A cover sheet should be completed.. See http://www.chem.unsw.edu.au/coursenotes/CHEM2041/ or Blackboard for downloadable cover sheets.
Occupational Health and Safety10
Information on relevant Occupational Health and Safety policies and expectations at UNSW: www.riskman.unsw.edu.au/ohs/ohs.shtml School of Chemistry OH&S policy and requirements see laboratory manual and WebCT. To be admitted to a laboratory, you must wear safety glasses, a lab coat and covered shoes (no thongs, open sandals or clogs). You must also complete all safety pre-lab work, risk assessment or other prescribed preparation relating to carrying out safe laboratory work. Visitors are not allowed to undergraduate laboratories without the permission of the lab supervisor.
Assessment Procedures UNSW Assessment Policy11
Candidates for CHEM2041 must demonstrate a satisfactory performance in both laboratory work and the written examination. A mark of !60% overall in the continuous assessment components is required to pass the course. A mark of !40% overall in the exam components is required to pass the course. If either of these conditions are not met, the course will be failed (even if the total mark is !50%). Laboratory reports and analytical results both contribute to the final laboratory mark.
Equity and Diversity
Those students who have a disability that requires some adjustment in their teaching or learning environment are encouraged to discuss their study needs with the course Convenor prior to, or at the commencement of, their course, or with the Equity Officer (Disability) in the Equity and Diversity Unit (9385 4734 or http://www.studentequity.unsw.edu.au/ http://www.equity.unsw.edu.au/disabil.html). Issues to be discussed may include access to materials, signers or note-takers, the provision of services and additional exam and assessment arrangements. Early notification is essential to enable any necessary adjustments to be made.

UNSW Academic Honesty and Plagiarism
What is Plagiarism? Plagiarism is the presentation of the thoughts or work of another as one’s own. *Examples include: • direct duplication of the thoughts or work of another, including by copying material, ideas or concepts from a book,
article, report or other written document (whether published or unpublished), composition, artwork, design, drawing, circuitry, computer program or software, web site, Internet, other electronic resource, or another person’s assignment without appropriate acknowledgement;
• paraphrasing another person’s work with very minor changes keeping the meaning, form and/or progression of ideas of the original;
• piecing together sections of the work of others into a new whole; • presenting an assessment item as independent work when it has been produced in whole or part in collusion with other
people, for example, another student or a tutor; and • claiming credit for a proportion a work contributed to a group assessment item that is greater than that actually
contributed.† For the purposes of this policy, submitting an assessment item that has already been submitted for academic credit elsewhere may be considered plagiarism. Knowingly permitting your work to be copied by another student may also be considered to be plagiarism. Note that an assessment item produced in oral, not written, form, or involving live presentation, may similarly contain plagiarised material. The inclusion of the thoughts or work of another with attribution appropriate to the academic discipline does not amount to plagiarism. The Learning Centre website is main repository for resources for staff and students on plagiarism and academic honesty. These resources can be located via: www.lc.unsw.edu.au/plagiarism The Learning Centre also provides substantial educational written materials, workshops, and tutorials to aid students, for example, in: • correct referencing practices; • paraphrasing, summarising, essay writing, and time management; • appropriate use of, and attribution for, a range of materials including text, images, formulae and concepts. Individual assistance is available on request from The Learning Centre. Students are also reminded that careful time management is an important part of study and one of the identified causes of plagiarism is poor time management. Students should allow sufficient time for research, drafting, and the proper referencing of sources in preparing all assessment items. * Based on that proposed to the University of Newcastle by the St James Ethics Centre.
