TBR Chemistry Ch. 5 Exam Questions & Answers 2024 Buffer - ANSWER-a solution where pH remains relatively constant after the addition of either strong acid or strong base. Can be made by combining a conjugate pair in roughly equal mole portions (must be weak acid/base pair). The addition of strong base or strong acid shifts teh ratio of weak acid (HA) to its conjugate base (A⁻), but the pH does not change, if the A⁻:HA ratio is close to 1.0 Can also be made by partially titrating a...
