Curricular Compentecy Explanation

A titration is a form of determining the concentration of a solution. The process during a titration lab would consist of a solution mixed/added to a substance until a reaction occurs as the final product. In lab 20C, the objective was to titrate a known solution of hydrochloric acid with unknown concentration levels incorporated in a standardized sodium hydroxide, and to utilize the titration data to calculate the molarity of the hydrochloric acid alongside. Titration was used by using a known base, in this case, NaOH ((standardized)sodium hydroxide)) with the initial volume of 1.75 mL for the first (rough) trial out of 4, and had an uncertainty of 0.05 mL. The way to find out when you’re getting to the endpoint/equivalence point for this lab is mark down and notice the duration of the reaction occurring, and for 20C, it was measuring the time of how long the colour pink stayed consistent in the solute as it tells you when you get to the ending point of your experiment. The results of the experiment were satisfactory although I had to do an extra trial due to complications.

Unit Core Competency Self-Assessment

I felt that my experience of communication shined the brightest out of the other competencies. I demonstrated lots of communication skills between my partner and I by as we took turns with each procedure. Although there was confusion which lead to us having to do an extra trial, we communicated the frustration in a positive manner which I think got us through the experiment while still being sane and taught us that nothing will go the way you want it even if you do nothing wrong.
