Explanation: pH 7 is neutral, with equal H+ and OH-
pH is -log(H+ Molar Concentration) and at pH7, H+ and OH- are both at a concentration of 10^-7
A more acidic solution has more H+ than OH-, so it is a higher concentration than 10^-7 and therefore pH lower than 7. Conversely, a pH>7 means a higher concentration of OH- and lower concentration of H+
