Scenario
Chemical equip, a major chemical factory, recently hired me as a technical assistant.
To complete my induction period and advance within the company, I must review and
assess my success in the procedures and techniques that I have been involved in so
far, which include titration, colorimetry, calorimetry, and chromatography. In order
to improve and use these skills, I need to recognise the core practical and personal
competencies I have demonstrated. My own results, interpersonal skills, and
professional practise must all be assessed. A senior technician will evaluate the
report I write.
I understand that there are specific standards and regulations that must be followed when
participating in experiments, and I have done so throughout, assuring the application of a safe
working environment. Throughout the experiments, I learnt a variety of lab skills that will help
me not only now, but also later in life, such as when I attend university.
FOR ASSIGNMENT 2A:
I learned how to use titrations to determine the concentration of an unknown substance.
Titration is a sensitive analytical method that lets you determine an unknown concentration
of a chemical in solution by introducing a known concentration of another chemical I also
recorded my mistakes and errors from these tests.
So, when I use titration next time, I'll be able to reduce the number of errors I make. Some
the of the common mistakes that can be made during titration experiments are: end point
error (The end point of a titration is when the reaction between the two solutions has
stopped), misreading the volume, errors in concentrations, using the equipment incorrectly,
and other human or equipment errors (Human error includes using selecting the wrong
reagents or using the wrong amount of indicator and Equipment error typically is in the
burette, which can develop leaks over time. Even a small loss of fluid will affect the results of
the titration. So, if I practise more, I'll be able to enhance my skills, reduce my errors, and produce
more accurate and trustworthy outcomes.
Another skill that I have learned is the ability to
accurately work out unknown concentrations of
substances using two different techniques,
these being titration and colorimetry. I can do
this correctly by following each of the methods
and then using the correct formulas/equations
and rearranging them to work out each of the
unknown concentrations of a particular
substance. This skill can be transferable into
other experiments where it is necessary to use formulas and equations to work out
something, as I would have knowledge of how to rearrange and set out the formula, to suit
the thing I need to work out. [IMAGE 2]
