2. Una solución acuosa de amoníaco \( \mathrm{NH}_{3} 0,25 \mathrm{M} \) tiene un Kb de \( 1,8 \times 10^{-5} \), presenta disuelta una sal de cloruro de amonio \( \mathrm{NH}_{4} \mathrm{Cl} \) en una concentración de \( 0,45 \mathrm{M} \). a. Calcule el pH teniendo en cuenta ambas sustancias disueltas. b. Calcule el pH suponiendo que solo está presente el amoníaco. c. Escriba una conclusión teniendo en cuenta los resultados de los incisos a y b.
