Is lioh a weak base
Witryna5 Weak Bases • Unlike strong base that contain OH ‒ and dissociate in water, the most common weak bases produce OH ‒ ions by accepting a proton from water. • We quantify the extent of ionization of a weak base with the base dissociation constant K b • We can also calculate the percent dissociation of a base: Percent dissociation = [OH ‒] … Witryna6 kwi 2024 · Base is the substance that can produce OH⁻ ions in the solution. So, NaOH, KOH, and NH₃ are bases because they can produce OH⁻ ions in the solution. But, …
