WebCheck the pH slope in pH 7 buffer regularly. The slope should be greater than 92% (53.5 mV/pH @ 20°C or 54.4 mV/pH @ 25°C).The offset (as measured in fresh pH 7 buffer) should be +/- 30 mV for new electrodes and +/- 59 mV for aged electrodes to enable auto-buffer recognition during calibration.. How to check your pH electrode slope. Select the … WebTherefore, this buffer would only be effective at a range of plus or minus one from 4.74, so about 3.74 to approximately 5.74. The ammonium cation has a pKa value equal to 9.25 at 25 degrees Celsius. Therefore, the ammonium-ammonia buffer is effective plus or minus one of this pKa value, so approximately 8.25 to 10.25.
