Liliya Karapunarly 10.14.2017 2591143 Acid-Base Titration Lab Report Introduction : Titration is a process used to determine and concentration of a solution when it is reacted with another solution. Specifically, in this experiment hydrochloric acid solution and 0.1 M sodium hydroxide solution were titrated to determine the unknown concentration of HCl. A pH sensor was used to graph the changes in in pH as NaOH solution was added drop by drop to HCl solution by a reagent reservoir. The starting point and the end point of NaOH solution in the reservoir was determined, and the equivalece point was then calculated to determine where the most rapid pH change occurred. Once the volume of the titrant at the equivalence point was determined, the molarity equation was used to determine the concentration of HCl. Materials & Methods : Chemicals/Reagents: Approximately 40mL of 0.1 M NaOH 5mL of HCl 40mL DW Instruments/Glassware: 1 100 mL beaker 2 250 mL beaker pipet 1 60 mL reagent reservoir 1 Ring stand pH sensor LabQuest Methods:
