(a)
To calculate: The number of water molecules that are ionized in 1L of pure water at pH 7.0
Concept introduction: Ionization process is the continuous formation of splitting molecules to their particular cations and anions. Water is self-ionized, in which water molecule loses a proton H+ and forms a negatively charged ion OH-. pH of a solution is denoted as the negative logarithm of the hydrogen ion concentration of that solution. The pH in a solution decreases as H+ ion concentration increases in the solution.
(b)
To calculate: The percentage of the number of water molecules that are ionized in 1L of pure water at pH 7.0.
