Do bases have a high or low number
WebWeak acids and the acid dissociation constant, K_\text {a} K a. Weak acids are acids that don't completely dissociate in solution. In other words, a weak acid is any acid that is not a strong acid. The strength of a weak acid depends on how much it dissociates: the more it dissociates, the stronger the acid. WebAug 12, 2024 · Earlier, we said that most reactions can be called either Lewis acid/base or redox. In a Lewis acid/base reaction, an electron pair from the base is shared with the acid. What this really means is that the base has a HOMO that is pretty high-energy (a lone pair), and the acid has a LUMO that is pretty low energy.
