Consider a buffer solution containing 0.040 M ammonia (NH3) and 0.060 M ammonium chloride (NH4Cl). What is the pH of the resulting buffer solution after adding 5.0 mL of 1.0 M sodium hydroxide (NaOH) to 1 L of this buffer? Assume that the volume change upon addition of sodium hydroxide into the buffer is not significant. The Ka of NH4+ is 5.70 x 10-10.
