WebWhat is pH scale. The pH scale is used to identify how acidic a particular object is. pH values range from 0 to 14 on a 1 to 14 scale. A pH value of 7 indicates that the solution is neutral. This is why the pH value of water is also 7; which is considered neutral – neither basic or acidic. Rain water has a pH value between 5 and 5.5, which is ... WebIn chemistry, pH (/ p iː ˈ eɪ tʃ /), also referred to as acidity, historically denotes "potential of hydrogen" (or "power of hydrogen"). It is a scale used to specify the acidity or basicity of an aqueous solution.Acidic solutions (solutions with higher concentrations of H + ions) are measured to have lower pH values than basic or alkaline solutions.
