Conditions For Scaling In Pipelines – Ph In Glycol Solutions

摘要

If a glass electrode calibrated in aqueous pH standards is usedto measure H+ concentration in aqueous glycol solutions theresult will be in error due to the large change in solventproperties. Based on strong acid – strong base titrations inglycol solutions it is possible to calibrate glass electrodes. Thetitration does not only give the calibration constant for theelectrode, but also the autoprotolysis constant for the solventcan be determined. The calibration method makes it possibleto determine acid constants in glycol bypotentiometric titration.
