In chemistry, pH , also referred to as acidity, historically denoting "potential of hydrogen" (or "power of hydrogen"), 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 … See more The concept of pH was first introduced by the Danish chemist Søren Peter Lauritz Sørensen at the Carlsberg Laboratory in 1909 and was revised to the modern pH in 1924 to accommodate definitions and measurements in … See more Pure water is neutral. When an acid is dissolved in water, the pH will be less than 7 (25 °C). When a base, or specifically an alkali, is dissolved in water, the pH will be greater than 7.
