4. La acidez de una solución se mide por su pH de acuerdo a la fórmula pH = - log ( \( \mathrm{H}^{+} \)) endonde \( \mathrm{H}^{+} \)es la concentración de iones hidrógeno en moles por litro. El pH del agua pura es 7 . Una solución es ácida si su pH es menor que 7 , y es alcalina o básica si supH es mayor que 7 . a Calcule el pH de la sangre: \( 3,9 \times 10^{-8} \) moles/litro y de la leche: \( 4 \times 10^{-7} \) moles,litro. b. ¿Cuántas moles de iones hidrógeno están contenidos en unlitro de lluvia ácida cuyo pH es 5,0?
