Curricular Competency Explanation

A titration is the adding of a known substance to another known substance in order to create a desired concentration. In this lab a titration was used to add sodium hydroxide in order to neutralize hydrochloric acid. The endpoint of a titration is when you reach a desired concentration of the liquid in question. In this lab we knew that we reached the endpoint of our titration when the hydrochloric acid had a light link tint from the phenolphthalein. When we achieved this pink tint we knew that the hydrochloric acid was neutralized which was the objective of this lab.

Core Competency Reflection

In our lab we had to communicate in an effective way in order to get the lab done on time. This is because there were lots of instructions and specific processes that we had to follow in order to achieve an accurate result. Throughout the lab we had to communicate because there were lots of items needed in order for the lab to take place this included a ring stand, Erlenmeyer flask, 3 beakers, paper towels, butterfly clamp, pippette and a burette. Communication was key in order to ensure that we were able to grab these items in an efficient and timely manner. We also had to communicate well in order to perform the lab procedures, because we had to know which chemical was in each container so that there were no mistakes that could compromise the lab. We also had to communicate which steps we had performed and the measurements we got in order to make sure that we were on the same page and had the same results as each other.
