Outline Description of Module
This module provides practice in essential aspects of laboratory chemistry, associated mathematical concepts, communication and study skills.
On completion of the module a student should be able to
- recognise and name basic types of chemical apparatus, and understand when and how they are used;
- represent chemical process by formulae and balanced equations;
- use correctly units and dimensions for range of physical quantities;
- understand types of titration techniques and know when each should be used;
- use the principles of chemical equilibria to explain experimental observations;
- deduce and analyse unseen redox equations;
- understand the concepts of precision and accuracy;
- understand the origin of common formulae based on their derivation from the application of mathematics to a set of assumptions and boundary conditions.
How the module will be delivered
22 2-hour lectures/workshops, 3 3-hour laboratory classes, 4 half-hour tutorials, 2 1-hour sessions of oral presentations
Skills that will be practised and developed
On completion of this module, a student will be able to:
- show an understanding of quantitative information, and use notations and symbols correctly;
- carry out calculations involving concentration, purity or chemical equilibrium;
- apply abstract mathematical concepts to practical problems in chemistry;
- use word processing and spreadsheet software;
- demonstrate basic written and oral presentation skills;
- use common laboratory equipment appropriately and safely;
- use standard formats for reporting experimental work.
How the module will be assessed
Achievement of most of the learning outcomes will be assessed by a series of workshops, consisting of short class tests. In addition students will prepare a CV, and give two oral presentations. There will also be three sessions of practical work, in which students' laboratory skills will be assessed.
