  • This is a distinction awarded assignment. "Equipment needs to be calibrated to ensure results produced are accurate and precise. Depending on whether readings are within the tolerance limits or not, action may need to be taken to calibrate equipment. The tolerance for the accuracy of equipment should be within 2%. When calibrating glassware, the temperature needs to be constant, and a good analytical scale needs to be used. Calculations needs to be done to counter the effects of the glass an...

  • This is a distinction awarded assignment. "TLC is a highly versatile separation method that is widely used to analyse a variety of substance classes, including pesticides, steroids, alkaloids, lipids, nucleotides, carbohydrates, and fatty acids. In this technique it will be used to analyse plant pigments and amino acids. Components of a mixture will be identified using chromatographic techniques and by calculating the retention factor value, unknown solutions can be identified. Thin layer ch...

  • This is a distinction awarded assignment about the personal review (Aim D) for the Unit 2 in the first year of L3 Applied Science Btec. "As I was homeschooled I did not have access to a laboratory, nor did I complete any secondary school science experiments. All my experience is from home chemistry kits and researching history’s scientists. Unit 2 was a steep learning curve for me, and many new skills have been learnt and developed in a short time span. Research has aided my growth and I ...
