Acid-Base theories and concepts
Explain the Acid - Base Theories and concepts? 1) Classical concept / Arrhenius concept According the swedish scientist Svante Arrhenius : Acid : "An acid is H⁺ containing substance which donate H⁺ ion on dissolving water. HCl ➝H + Cl⁻ Base : A base is OH containing substance which donate OH ion on dissolving water. NaOH ➝ Na⁺ + OH⁻ Advantages : Can calculated heat of neiterllization . Can find Acid-Base strength. Catalytic properties can be determine. Defects: Limited to aqueous medium only . Don't suitable for gaseous phase reaction . It contain acid and bases but not H⁺ and OH⁻ 2)Solvent System Definition: According to solvent system concept : Acid : In the solvent system definition: A solute which increase the concentration of cation generated by the auto ionization of solvent is called acid. NH₄Cl ➝ NH⁺₄ + Cl⁻ Base : A solute which increase the concentration of anion generated by the auto ionization of solvent is called base . NaNH₂ ➝ NH⁺₄...
