Acid-base Equilibrium

Introduction to Acid Base Equilibrium

Acids and bases are essential in chemistry, defined by their ability to donate or accept protons (Bronsted-Lowry) or electron pairs (Lewis). Acids typically release H⁺ ions, while bases release OH⁻ ions. Understanding acid-base concepts is crucial for mastering chemical reactions, pH balance, and titration processes.
