Sin embargo, cuando estas disoluciones son extremadamente diluidas, el cálculo de su pH de la forma descrita conduce a resultados incongruentes. Por ejemplo, una disolución 10-8 M en ácido clorhídrico, da lugar a un pH 8. En estos casos, hay que tener en cuenta la contribución de los protones procedentes de la disociación del agua. Ya que en agua pura la concentración de protones es 10-7 M, vemos que este aporte de protones es mayor que el de la cantidad de HCl añadida a la disolución.
