Calculate the pH of 1.0 L of the original buffer in Example upon addition of 0.010 mol of solid NaOH
EXAMPLE

Using the Henderson—Hasselbalch Equation to
Calculate the pH of a Buffer Solution Composed of a Weak Base and Its Conjugate Acid Use the Henderson—Hasselbalch equation to calculate the pH of a buffer solution that is 0.50 M in NH3 and 0.20 M in NH ₄ CI. For ammonia, pk _b = 4.75.
