Question

Calculate the pH of a 0.96 M solution of a weak BOH, for instace NH4OH, often written as NH3,

and 0.97 M of a salt derived by its conjugate acid, BCl, like NH4Cl.

The base dissociation constant, Kb , is 3.86e-6.

What is the pH if 35 mL of 0.153 M of a strong acid, like HCl, is added to 100 mL of the buffer solution? What if a strong base, like NaOH, is added with the same ammount instead ?
