In chemistry, pH (/ p iː ˈ eɪ tʃ / pee-AYCH), also referred to as acidity or basicity, historically denotes "potential of hydrogen" (or "power of hydrogen"). [1] It is a logarithmic scale used to specify the acidity or basicity of aqueous solutions.Acidic solutions (solutions with higher concentrations of hydrogen (H +) ions) are measured to have lower pH values than basic or alkaline ...
