This means these quantities must both equal 10-7 M. If we put [H+] = 10-7 M into the equation for pH: pH = -log10[H+] we get pH = 7 for neutrality. Acid and Base pH Acid solutions have pH < 7. pH values lower than 0 are possible. Basic solutions have pH > 7. pH ...

After calibration, pH meters will typically display the slope of the electrode in either mV/pH (i.e. the Nernst slope), as a percentage, or both. We are often asked what this percentage, termed the electrode efficiency, actually means. ...
During pregnancy, prescribe metronidazole, 500 mg orally bid or 250 mg orally tid for 7 days, or clindamycin, 300 mg orally bid for 7 days. Some prefer to use oral rather than topical therapy in pregnancy because it may also treat subclinical coinfections. Vaginal treatment is less preferred...
If your pH measurement is higher than expected, this means that it would be alkaline if it falls within the7-14 pH range. Some plant species can still thrive in more alkaline environments, which is why it's important to do your research beforehand. For other crop types, dealing with a ...
It is generally advisable to invest in a pH meter/electrode combination that offers resolution and accuracy of 0.10 pH units or better.” [7] Barb Ingham at the University of Wisconsin says, Accuracy is listed as a range of +0.XX pH units. This means that the meter may read so many ...
The present invention relates to a process for adjusting pH to a fixed value and a stoichiometric pH-stat means (10) for completing the process. The process comprises the steps of (a) measuring a pH-value in a system of known reactants with reactions of known courses; (b) establishing ...
If it measures low on the scale (pH1), it means the substance is very acidic. If it measures high on the scale (pH7), the substance is very alkaline. You’re probably pretty familiar with acids: Citrus, like lemon juice, is acidic. You may be less familiar with alkaline things, but...
the pH scale usually ranges from 0 to 14.Aqueous solutionsat 25°C with a pH of less than 7 areacidic, while those with a pH greater than 7 are basic oralkaline.A pH levelof 7.0 at 25°C is defined as "neutral" because the concentration ...
