Alkaline error associated with the use of glass membrane pH electrodes for pH measurements will yield: Select one: O a. False low pH readings at low sample pH values due to the positive interference of Na+ and other alkali cations on the potential (EMF) of the glass membrane O b. False low pH readings at very high sample pH values due to positive interference of Na+ and other alkali cations on the potential (EMF) of the glass membrane O c. False high pH reactings at low sample pH values due to the negative interference of Na+ and other alkali cations on the potential (EMF) of the glass membrane O d. False high pH readings at very high sample pH values due to positive interference of Na+ and other alkali cations on the potential (EMF) of the glass membrane O e. Both false low and false high values depending on experimental setup
