Modern Titration A second experiment was performed to determine the molarity of a second soda solution however, this time the modern titration rules were used. First, 20 mL of Jones Green Apple was collected in a beaker. The soda solution had already been prepared for the removal of carbonic acid by boiling before the experiment began. No phenolphthalein indicator dye was used for this titration. The soda solution was again diluted to 100mL with NaOH and then placed into a 250 mL beaker which was then placed on a stir plate with a stir bar. A 50.0 mL buret was pre-rinsed and filled to 0.00mL with NaOH titrant solution. The Labquest device was then turned on and set to record and the pH probe was then placed into the beaker with the solution. A Rapid titration was done until the pH reached 6.0 and then it was done by drops till the pH reached 10.5. The Labquest device was used to record the volume of titrant and pH quantities at every increase of 0.1-.02 pH. After the titration had been completed, the data from the Labquest was transferred over to the lab computer to be used on logger pro. This procedure was repeated two more times for a total of three titrations performed. Calculations of Titrations 2

The Calculation procedures for both the traditional and modern titrations are both similar except for the way the endpoints are determined. The endpoints for the traditional titrations are calculated by taking the Final volume of titrant and subtracting it from the Initial volume of titrant used in the buret. However, in the modern titration the endpoints are determined on the logger pro graphs. Here this was done by plotting the NaOH volume data on

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
