Lab 11A: Titration of Hydrochloric Acid SCH 3U

Introduction Purpose Apparatus Materials Procedure Observations Discussion Conclusion Links

Conclusion: I conclude that from the results of our experiment, the concentration of Hydrochloric acid in the sample is 0.103 mol/L. The result of this experiment is considered to be accurate because the data collected from both trials correspond to each other. The measurements taken were accurate because we use the readings from the burets. We also learned to read the proper colour signal of the Phenolphthalein solution before it got too dark. Therefore, our endpoint should be quite accurate. The only possible source of error might be whether the flask used had contaminant. Therefore, our finding is that the concentration of Hydrochloric acid in the sample is 0.103 mol/L. < Back to Discussion
