conjugate base


August 13, 2022

A conjugate base is the base formed when an acid (in water) is ionized. From the acid-base equilibrium it follows that the stronger the acid, the weaker the base, and vice versa. When the K-values ​​of the acid and the conjugate base are multiplied, the K-value of water always comes out. In formula: Kz · Kb Kw (Kw always 10−14). Some examples of this are HF with the conjugate base F−; H2CO3 with HCO3− as conjugate base or HCl with Cl− as conjugate base. Weak acids or bases with corresponding salt form a buffer solution. Example of such a buffer: CH3COOH+CH3COONa (acidic buffer). A weak acid has a strong conjugate base
