Description
The study of chemistry is central to an understanding of the physical world, and is fundamental to the study of biology, geology, and environmental science. This subject builds on and develops further the material introduced in 65111 Chemistry 1. The subject is divided into the broad areas of physical chemistry (equilibria, kinetics and thermochemistry) and organic chemistry (carbon compounds and their reactions, including biological molecules such as proteins, sugars and nucleic acids). The study of physical chemistry allows for the explanation and prediction of chemical reactivity and energetics, while organic chemistry provides the building blocks for understanding the complexity of the natural world.
This subject also covers extension topics in areas such as inorganic chemistry, analytical chemistry and forensic chemistry.
Subject learning objectives (SLOs)
Upon successful completion of this subject students should be able to:
| 1. | Explain key principles in physical and organic chemistry and relate these to modern chemical research and professional practice |
|---|---|
| 2. | Measure and make predictions about the yield, rates and mechanisms of chemical reactions, and the energy changes involved in those reactions |
| 3. | Apply the principles of chemical equilibrium to aqueous acids and bases, buffer solutions and sparingly soluble inorganic salts |
| 4. | Classify the structure and reactivity of a range of organic compounds (including biological molecules) according to the functional groups they possess and their stereochemistry |
| 5. | Apply practical skills to perform basic organic synthesis and solvent extraction, and to determine the presence of molecular functional groups through chemical tests and spectroscopy |
| 6. | Collect and analyse physical chemical data in such a way that meaningful conclusions can be drawn |
| 7. | Communicate chemical concepts to a range of audiences, both verbally and in writing |
Contribution to the development of graduate attributes
1. Disciplinary knowledge and its appropriate application
This subject aims to develop students’ understanding of chemistry and its significance in other scientific disciplines. This subject will develop the student’s knowledge of chemistry through the lecture/tutorial sessions and online self-test quizzes, while practical skills and knowledge will be developed in the laboratory sessions. These concepts are assessed in the laboratory quizzes, mid-session and final exams.
3. Professional skills and their appropriate application
In the practical sessions, students will gain understanding and proficiency in a number of skills critical to their development as professional scientists. These skills include problem solving, experimental procedures, teamwork and professional conduct in the laboratory. The assessment of these skills will be covered in all laboratory-based assessment tasks. Problem solving skills will be developed by the in-lab questions and assessed in the laboratory quizzes; experimental skills will be developed during practical sessions and assessed in the practical examination. Teamwork and professionalism in the laboratory will be developed and assessed through the professional practice points.
6. Communication skills
Communication skills are an essential part of the development of a professional scientist. Throughout the session students will be required to communicate their results in their lab manuals, which will be assessed during the laboratory session. As part of the assessment of the stereochemistry model-building practical, students will present and explain models of chiral compounds to their peers and demonstrators, and will be assessed on the clarity and accuracy by which they do this.
Teaching and learning strategies
This subject will be delivered through lectures, practical classes and independent learning activities.
There will be 4 hours of lectures each week. These sessions introduce and explain key principles in physical and organic chemistry and relate them to modern chemical research and professional practice. Students are expected to complete assigned readings before class and be prepared to discuss the content in the classroom. Lecture time also offers opportunities for questioning and clarification of the subject material. Attendance is recommended at all lectures to develop a complete understanding of the content (students who do not attend lectures often do not pass this subject). The fourth, "advanced" lecture each week will cover specialised topics in organic, analytical and forensic chemistry, and students will be assessed using in-lecture quizzes based on the lecture content, after an opportunity to discuss this content among themselves in small groups.
The laboratory classes are an essential part of the subject as they will consolidate a student’s understanding of theoretical concepts delivered in the lectures. Students will usually work in pairs to develop important practical skills that are highly sought after by future employers, including an understanding of laboratory safety and other important professional experience. Attendance for the laboratory program is compulsory. Chemistry 2 Advanced students will complete modified versions of two Chemistry 2 practicals, employing spectroscopic techniques to identify organic compounds.
Numerous independent learning activities with structured feedback are employed in Chemistry 2 and Chemistry 2 Advanced, accessed through UTSOnline and Mastering Chemistry. These include post-lecture activities such as online self-quizzes designed to test the understanding of concepts encountered in class. The completion of pre-laboratory exercises delivered online will be compulsory for all students before entering the laboratory sessions. Students get three types of feedback in prac classes on a weekly basis: quiz mark (discipline content), professional practice points (professional conduct), experimental mark (based on results and effort).

- Solubility equilibria. Ksp. Common Ion Effect.
