The weak base-conjugate acid buffer used in this laboratory consists of a weak base ammonia, NH3, and its conjugate acid ammonium chloride, NH4Cl. If the NH3 concentration is 0.05 M and the NH4Cl concentration is 0.05 M, what is the pH of the buffer? Kb for NH3 is 1.8*10^-5

Use the Henderson-Hasselbalch equation.
base = 0.05 M
acid = 0.05 M
