Unknown Acid Lab

Today we began a lab in which the task is to calculate the molar mass of an unknown acid. This was accomplished by making a standard of KHP solution, then dissolving some of the unknown acid in water. We titrated the solution using NaOH as a base and Phenolphthalein as an indicator. Once done with that, we did some calculations and found out to our surprise that it was the aspirin we had made 1st semester!

Here is a video for help with understanding titrations.
