Meaning

Acid-base; acid and base as a paired concept in chemistry. Refers to the system of acids and bases and their reactions.

Used as a modifier in compound terms such as 酸塩基反応 (acid-base reaction), 酸塩基平衡 (acid-base equilibrium), and 酸塩基触媒 (acid-base catalyst). Foundational to understanding pH, neutralisation reactions, and biological buffer systems.

Examples
