This unit standard does not replace any other unit standard and is not replaced by any other unit standard. 

PURPOSE OF THE UNIT STANDARD 
A person credited with this unit standard is able to:
  • Demonstrate knowledge of elementary acid-base titrations,
  • Prepare for elementary acid-base titrations in an analytical laboratory,
  • Perform elementary acid-base titrations in an analytical laboratory,
  • Report on the results of the acid-base titrations.

    This unit standard is for anyone who has to perform elementary acid-base titrations in an analytical laboratory.

    This unit standard will contribute to the full development of the learner by providing recognition, further mobility and transportability within the field of manufacturing and assembly.

    UNIT STANDARD RANGE 
    The scope of this unit standard is for anyone who has to perform elementary acid-base titrations in an analytical laboratory.

    In the context of this unit standard, acid-base titrations refer to titrations used for the preparation of standard solutions.

    The level assigned to this unit standard is appropriate because the process is moderate in range, established and familiar and offers clear choices of routine responses. The learning demand employs basic operational knowledge and readily available information. The application of this unit standard is to qualify the person for certification in sub-trades.
