Experiment 14: Titration of Antacids General Chemistry I and II Lab Manual Dakota State University page 158 of 232 2. Choose “calibrate”; put some of the higher pH buffer to your small cup. Put the pH probe into the buffer and allow a few minutes to equilibrate. Type the correct value into the “high pH” space (for example, if it is the pH 10.00 buffer solution, type 10.00 into this space). As soon as the reading seems to have stabilized, click “read”. Return the buffer solution into the correct “used buffer” container. 3. For the low pH calibration, refill your little cup with the low pH buffer solution. Empty out your calorimeter. Put the pH probe into the buffer and allow a few minutes to equilibrate. Type the correct value into the “low pH” space (for example, if it is the pH 2.00 buffer solution, type 2.00 into this space). As soon as the reading seems to have stabilized, click “read”. Return the buffer solution into the correct “used buffer” container. If you followed these instructions carefully, your Pasco system should be ready.
