WebAug 19, 2024 · A buffered solution contains 0.25M NH3 (Kb = 1.8 x 10-5) and 0.40M NH4Cl. Calculate the pH of this solution. The major species in the given solution are: Ammonia (NH 3) Ammonium cation (NH 4+) Chloride ion (Cl –) Water (H 2 O) Here the Cl – ion is a weak base and water can behave as acid as well as base. The calculations are as follows: WebA titration curve visually demonstrates buffer capacity. The middle part of the curve is flat because the addition of base or acid does not affect the pH of the solution drastically. This is the buffer zone.
