Its when the acid and the bases both use oxygen as a compromediac molecule, therefore leaving the pH scale on an unportable metre. Although many speculate whether the hydro-components in both these type of akalies but this is often not excused.
A pH meter measures the pH of a solution utilizing a glass electrode and a voltmeter.
The pH is determined with a pH-meter.
A pH meter shows how acidic or basic a substance is
Combine electrod used in ph meter
A pH meter determines acidity or alkalinity of a substance.
The pH is determined with a pH-meter.
You need a pH-paper or a pH-meter.
We can use a pH paper.
pH indicator, pH paper, and a pH meter. You can find them on this page http://onsager.bd.psu.edu/halmi/chem3pHS05.pdf
Using a calibrated pH-meter with correction for temperature and slope.
Using a pH-meter the measurement is more accurate and sure.
Not the pH-meter, but the electrode.
