pH-value (potassium chloride)

pH (KCl)

The pH-value in a suspension of sample material and a diluted potassium solution corresponds to the potential acidity.

The hydrogen-cations adsorbed to the sample constituents are replaced by potassium cations and are therefore measurable in the suspension. The resulting pH is about 0.3-1.0 units lower compared to the pH in a suspension with pure water. The potential acidity is important because cation exchange may also occur under natural conditions and lead to significant drops in pH.
