Formula and explanation
For dilute solutions of a monoprotic strong acid (e.g., HCl, HNO₃), it dissociates completely in aqueous solution. The hydrogen ion concentration [H⁺] is equal to the initial concentration of the acid c₀. Formula: [H⁺] = c₀ pH = - lg c₀ Applicable conditions: Dilute solutions of monoprotic strong acids (typically c₀ > 10⁻⁶ mol/L). At very low concentrations, the ionization of water must be considered. Brief description: This is the simplest case for calculating the pH of a strong acid solution.
