Acid-Base Titration

Initial volume of the buret: 0.14±0.05mL
Final volume of the buret: 15.96±0.05mL

Curricular Competency Explanation

A titration is way to find a concentration of a unknown solution by using the concentration of a known solution. In this lab, the titration is using the known NaOH concentration to find the unknown HCl concentration. The endpoint of the titration is when the indicator changes colour. This shows that the acid-base is neutralized. The endpoint in this titration, is when the indicator is the lightest possible shade of pink for at least 30 seconds. The result of my lab were that the concentration of the HCl was 0.148M to get the lightest shade of pink.

Core Competency Reflection

In this lab, I had to use a lot of communication. I had to collaborate with my lab partner in order to complete the lab. My lab partner and I had to get the correct equipment required for the lab which needed communication. We also had to split-up the tasks to get the lab done in time. Splitting up the tasks was very helpful because we had different strengths and we could still help each other out. Communication in this lab was very important, because the amount of NaOH had to be exact and added to the HCl very carefully. We took turns adding the NaOH in, so we both got practice doing it. During this lab we not only needed to communicate with each other, but also with the teacher. We needed to ask the teacher questions in order to successfully complete the lab. In the end, we were able to complete the lab and find the concentration of HCl.
