Professor Durand 22 October 2016 ANAL0417: Using Volumetric Glassware to Measure, Dilute, and Titrate and Acid Solution Abstract: The experiment that was performed consisted of determining the concentration of an acid by diluting it and then doing a titration with an aliquot and sodium hydroxide. The final results showed that the average acid concentration over 3 trials was 1.00M. Introduction: In order to determine molarity of HCl, we had to perform a method of analysis. A common one used in Chemistry is called titration. Titration is defined as the measurement of the volume of standard solution required to completely react with a measured volume or mass of the substance being analyzed 1 . A titration requires a buret, which held sodium hydroxide. Sodium hydroxide is a base, which could be used to neutralize the HCl. In order to conduct this experiment, the HCl needed to be diluted because the reaction requires more NaOH than what the buret can hold 1 . To be as accurate as possible, the buret shouldn’t be refilled in the middle of a titration. An aliquot of HCl was used for this experiment. An aliquot could be used because the
