You will practice finding the endpoints of titration curves using 1st derivative, and 2nd derivative using the software Curtipot (www2.iq.usp.br/docente/gutz/Curtipot_.html). The structure of KHP and its reaction with sodium hydroxide is shown below: Reagents/Supplies: pH meter with buffer and instructions for calibration.
The freeware software CurTiPot [27] was again used to analyze the obtained potentiometric titration curves (i.e., titrant volume versus measured pH). The 'Regression' module of CurTiPot To facilitate the mass transfer of CO2, the sample was stirred (500 min?1) during the first 5 min of treatment. Afterwards, the vessel was

Rivers transfer huge quantities of dissolved carbon towards the world's oceans, but not all of it gets there. This is due to the release of carbon from www.iq.usp.br/gutz/Curtipot.html). Task 1.

a diprotic weak acid with a pKa1 of 3 and a pKa2 of 4, using 0.100 M NaOH as the titrant. The fact that pKa2 falls within the buffer range of pKa1 presents a challenge that you will need to consider.
