The Arrhenius Groundbreaking Theory. Dissociation of Salts, Acids, and Bases • How Water Dissolves Ionic Compounds • How Covalent Compounds Dissociate in Water. Heterolytic and Homolytic Cleavage of Covalent Bonds. • They Come Together and Part Non-Stop. Chemical Equilibrium • Strong and Weak Electrolytes. Degree of Dissociation • Water, Acids, and Bases from the Perspective of Electrolytic Dissociation • The pH Scale. Acid-Base Indicators.
