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 solutions. WebIf you plug the hydrogen ion concentration of water (1 × 10 ^ {-7} −7 M) into this equation, you’ll get a value of 7.0, also known as neutral pH.
