Unit of competency
Modification History
Release 1. Supersedes and equivalent to MSL974017 Prepare, standardise and use solutions. Changes to Performance Criteria to remove requirements in relation to primary and secondary standards and indicators, equivalence points using indicators and graphical methods. Graphical methods removed from Foundation Skills. Superfluous terminology item removed from Knowledge Evidence and detail reduced in Assessment Conditions.
Application
This unit of competency describes the skills and knowledge to prepare, standardise and monitor the quality of solutions.
This unit of competency applies to laboratory technicians working in all industry sectors.
No licensing or certification requirements exist at the time of publication. However, regulations and/or external accreditation requirements for laboratory operations exist, so local requirements should be checked. Relevant legislation, industry standards and codes of practice within Australia must also be applied.
Pre-requisite Unit

Foundation Skills
This section describes those language, literacy, numeracy and employment skills that are essential to performance.
- Numeracy skills to:
- select and use primary and secondary standards and indicators
- determine equivalence points using indicators
- calculate the concentration of the solution with appropriate units and uncertainties given the chemical reaction for the titration
- recognise control results that are not within an acceptable range.
Other foundation skills essential to performance are explicit in the performance criteria of this unit
