SPEAK ABOUT PAST 3 ASSIGNMENTS IN DETAIL EVALUATION
Aims:
- Review and evaluate my performance of the procedures and techniques that I have been
involved in using so far (titration, colorimetry, calorimetry and chromatography)
- Identify the key practical and personal competencies I have shown whilst developing and
using these skills
- Evaluate my performance, interpersonal skills and professional practice.
Introduction:
I am a newly appointed technical assistant located at a large chemical plant known as chemcalequip.
In order to progress with the company, I have to review and evaluate my performance of the
techniques I was involved in using. These include titration, colorimetry, calorimetry and
chromatography.
Evaluation on assignment 2A:
In this assignment I had to carry out numerous practicals to find out the concentration of my
standard solutions and unknowns’ concentration and the end point. I had to develop a couple of
skills to achieve what was asked from me (i.e. Calibration of equipment, calculations, etc).
Skills at the start of course skills gained from unit 2 Skills to be developed
making standard solutions I have learnt how to dissolve To be able to decide the exact
solids to create standard amounts of solids that are
solutions required to make the standard
solution and get right values
to be able to dilute liquids I have learnt to dilute liquids to To be able to create my own
match the moles I need and dilutions with my own
concentration calculations
To be able to use a Pasteur pipette I have learnt to use a To be able to use other types of
graduated pipette pipettes
Performance of titrations I have learnt how to carry out To be able to use a variety of
titrations using a pH meter and probes to carry out titrations.
using indicator solution
Understanding concentration and be I have learnt how to calculate
able to calculate concentrations concentrations from other
solutions and using
absorbance to find unknown
concentrations
Understand what colorimetry is To be able to carry out To be able to carry out different
colorimetry with my own types of colorimetry
dilutions
To be able to calculate RFM, moles, To be able to link different
mass, volume and concentration equations to calculate moles,
and concentrations
Observation of work and reflecting I have learnt how to observe I need to work on my evaluations
