- pH - Wikipedia
In chemistry, pH ( piːˈheɪtʃ or piːˈeɪtʃ ; pee-AYCH) is a logarithmic scale used to specify the acidity or basicity of aqueous solutions Acidic solutions (solutions with higher concentrations of hydrogen (H+) cations) are measured to have lower pH values than basic or alkaline solutions While the origin of the symbol 'pH' can be traced back to its original inventor, and the 'H

- PH Definition Meaning - Merriam-Webster
The meaning of PH is a measure of acidity and alkalinity of a solution that is a number on a scale on which a value of 7 represents neutrality and lower numbers indicate increasing acidity and higher numbers increasing alkalinity and on which each unit of change represents a tenfold change in acidity or alkalinity and that is the negative logarithm of the effective hydrogen-ion concentration
