How is pH defined? A change of 1.0 pH unit corresponds to how much of a change in [H3O+]?
pH is defined as the negative logarithm of of the hydronium ion or hydrogen ion concentration.
pH = - log [H+]
pH is used to specify the acidity of a solution. In general,at room temperature
(a) if pH< 7, the solution is said to be acidic.
(b) if pH> 7, the solution is said to be Basic.
© if pH=7, the solution is said to be neutral.
