Curricular Competency Explanation

1. A Titration is a lab technique used to find the concentration of a substance in a solution.
2. In this lab, a titration was used to discover the unknown concentration of a substance with Sodium Hydroxide.
3. The endpoint in titration is the point where the indicator changes color. When the color changes, that mean that the reaction is complete. (The moles of the titrant should be equal to the moles of the substance being analyzed.)
4. I know that I have reached the endpoint of the titration when the substance changed color,. The goal was to find a very light pink color that stayed for at least 30 seconds, once the color stayed for 30 seconds, I knew that we had reached the endpoint.

Core Competency Reflection

Communication

My strategies for collecting relevant information for specific tasks include…

I work with my partner to figure out how to find answers to the objectives using the information that we learned in class, or using the textbooks. If we are both confused we usually ask for help so that we can get a better understanding on how to move forward.

In discussions and conversations, I help to build and extend understanding by…

I like to ask questions and re-read over lab instructions to ensure that I don’t make things difficult for my surroundings and the people around me so that we can do things correctly and not waste any time.

Collaboration

I know the group is working well together when I hear/ see…

I knew that my partner and I were working well together when we started to work on the trials quicker each time. By the fourth trial, we sped through and were confident that we knew what we were doing.
