WebA substance's pH is related to the balance of H+ (hydrogen) ions and OH- (hydroxide) ions. A substance with more H+ ions than OH- ions will have a pH below 7, and thus will be acidic. A substance that has an equal concentration of H+ and OH- is neutral (pH of 7). When the concentration of H+ is less than the concentration of OH-, the substance ... WebJan 26, 2012 · A solution with a pH between 5 and 7 is neutral, 8 or higher is a base, and 4 or lower is an acid.
