Solution of a base
WebAboutTranscript. Weak bases partially ionize in water to produce hydroxide ions. Because the ionization is not complete, the concentration of OH⁻ in a weak base solution is … WebMar 20, 2024 · A solution of a weak acid is also a buffer solution. When a weak acid reacts with a weak base an equilibrium mixture is produced. An acid base reaction is the removal of hydrogen ions from the acid and its addition to the base. The reception of proton by a base produces its conjugate acid, which is the base with a hydrogen ion added.
