IHS: Exam 3: ABG 100% REVISION 2023//2024 Acid • a molecule that can act as a proton (H+) donor. • Strong acid readily and irreversible gives up an H+, and a strong base avidly binds H+ Base • a molecule that can act as a proton acceptor. • A weak acid or base reversible donates H+ or reversible binds H+. Acidemia blood pH < 7.35 Acidosis is the process that lowers pH - H+ concentration in blood is increased Alkalemia blood pH > 7.45 Alkalosis is the process that rai...

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...
