Release 1

This version was released in MSL Laboratory Operations Training Package Release 2.0.

Supersedes and equivalent to MSL974001 Prepare, standardise and use solutions. Foundation skill information added. Range of conditions removed. Assessment requirements amended.

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.

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 and graphical methods
  • 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 acceptable range.

Other foundation skills essential to performance are explicit in the performance criteria of this unit.
