Problem
A chemist mixes 50.0 mL of 0.200 M aqueous ammonia (NH₃) with 25.0 mL of 0.250 M ammonium chloride (NH₄Cl). After mixing, the temperature is 25 °C and the total volume is the sum of the individual volumes. The pKa of the ammonium ion under these conditions is 9.25.
Determine the pH of the resulting solution.
