Predict its pH … Webb30 dec. 2024 · KCl is neither an acid nor a base. It is made from the neutralization reaction of the strong acid, namely hydrochloric acid (HCl) with a strong base, namely potassium hydroxide (KOH). The pH value of the aqueous solution of KCl is 7. Because strong acid and a strong base will neutralize each other effects and a neutral solution forms.

WebbpH (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 ...
