What is a titration? A titration in a chemistry experiment requires the use of a burette with a solution being poured into another solution with a known volume until the reaction is just complete. You can simplify this by saying its just like mixing two things until you reach the right spot. We used titration in our lab when we mixed an average of 14.23mL of NaOH into our Erlenmeyer flask that contained 10.0mL of HCl. Before mixing 3 drops of phenolphthalein was added to see the titration. The endpoint of a titration is when the reaction is complete and both solutions are mixed perfectly, we knew when we reached the endpoint of our titration when the pink color that we would see when mixing the liquids was taking longer to vanish, then when it would take 30s of the color being very light pinkish before vanishing. Our finished results was the titration taking an average of 14.23mL of NaOH to complete.

Collaborating Reflection

I can take on roles and responsibilities in a group; I do my share.

I was in a duo group during this lab experiment but was left to be solo after my group member got sick, he did some of the dirty work and he’s usually the one that does better on the physical lab part while I do most of the sheets. I was forced to relearn it by myself and take on both roles. I ended up doing all of my trials and getting the numbers we were expected to get. I also ended up completing the lab, and helping my sick group member complete it after I finished both the lab and the handout.
