Aqueous solutions at 25 °C with a pH less than 7 are considered ,acidic,, while those with a pH greater than 7 are considered basic (alkaline). When a pH level is 7.0, it is defined as 'neutral' at 25 °C because at this pH the concentration of H3O+ equals the concentration of OH− in pure water. pH is formally dependent upon the activity of hydronium ions (H3O+),(H+ is often used as a synonym ...
