Titration is a technique used in labs to determine the molarity of substances. In this lab, it was used to determine the molarity of an acid, HCl, by titrating it with NaOH. Phenolphthalein is used to indicate the equivalence point, which is when there is an equal amount of acid and base, as the solution will turn a very pale pink. In our experiment, we found that the average volume of NaOH used was 15.17ml +/- 0.1ml.

During this lab, I demonstrated communication skills as this lab was done with a partner. We communicated throughout the entire lab to ensure that we were following the correct procedures. At the point where we had to film and take pictures to demonstrate half-drops, we made sure to communicate with each other so that we took videos of everything we needed. We took turns taking half-drops and filming so that both of us could have videos. After we finished the lab, we communicated to put away the materials by asking questions when we didn’t know where something went and making sure that everything was returned to their designated spot.
