Alex Radzin Professor Chandu CHM 266 Section 12 10/10/17 Acid-Base Titration Lab Report Introduction: In this lab, a pH Sensor was used to monitor changed in pH as sodium hydroxide was added to a hydrochloric acid solution. The LabQuest was used to help graph pH vs. volume of sodium hydroxide added. The graph showed us the equivalence point of titration on the LabQuest. The results were used to calculate the concentration of the hydrochloric acid solution. 40 mL of distilled water was added into a 100 mL beaker and then 5 mL of HCl was added to that same beaker. A reagent reservoir, which held 40 mL of 0.1 M sodium hydroxide, was suspended in a ring stand above the beaker. The LabQuest was then started and the NaOH was slowly dripped into the beaker. It was also stirred to make sure that the solution was thoroughly combined. The HCl and NaOH solution was then graphed until there was a spike in the graph and then flattened out again. Once the graph was finished, it was used to find the moles of both HCL and NaOH. The LabQuest probe was what actually picked up the changes in concentration. The final state of the graph
