BTEC Level 3 Applied Science Unit 2- Practical Scientific Procedures and Techniques Learning Aim A: Undertake titration and colorimetry to determine the concentration of solutions

In this assignment you will read about how to correctly prepare and standardise solutions for colorimetry, the method used, results and an overall conclusion and to determine the concentration of copper (II) sulfate using colorimetry. Due to COVID and lockdown we did not carry out a titration experiment so did not write up in the assignment. Overall, I received a merit in this assignment and the unit overall. Distinction had been attempted but not met.
