This lab was very similar to the vinegar lab. We began by titrating KPH again to standardize the base. Then we proceeded to dissolve some of this unknown solid acid in water then we had to heat it and stir it as it is rather insoluble. We then titrated it however this would turn pink and then it would change back to clear. In the end our results were very good as we got about 179 and the actual mass was close to 180. Later we were told it is none other than the acetylsalicylic acid that we had cooked up at the beginning of the year!
