Write true or false for the following statement:
Mixing an acid or base with water results in an increase in the concentration of ions $(H_{3}O^{+} / OH^{-})$ per unit volume.

(FALSE) The statement is False.
When an acid or a base is mixed with water,it undergoes a process called dilution.
Dilution is the process of adding water to a concentrated acid or base,which results in a decrease in the concentration of ions $(H_{3}O^{+}$ for acids or $OH^{-}$ for bases) per unit volume.
Therefore,the concentration of ions per unit volume decreases,not increases.
