PH is simply a convenient way to denote hydronium ion concentration (usually in moles per liter or molarity). pH is calculated from the given concentration using the equation: pH = - log [H3O⁺]

To find [H3O+] from the given equation, we apply the antilog.

[H3O⁺] = 10⁻⁽pH⁾ or ten raised to the negative value of pH

A solution with a pH of 3.43 has a hydrogen ion concentration of 3.7154x10^-4 moles per liter.
