Para calcular el pH de la sustancia, primero necesitamos encontrar el pOH usando la concentración de iones hidroxilo (\(OH^-\)). La fórmula para calcular el pOH es: \[ pOH = -\log[OH^-] \] Sustituyendo la concentración de iones hidroxilo: \[ pOH = -\log(8.59 \times 10^{-13}) \approx 12.07 \] Luego, utilizamos la relación entre pH y pOH: \[ pH + pOH = 14 \] Por lo tanto: \[ pH = 14 - pOH = 14 - 12.07 \approx 1.93 \] Así que el valor de pH es \( 1.93 \).
