WebSep 28, 2016 · The hardness of a lewis acid increases with increasing positive charge, as the electron density is more concentrated. Therefore, Cu2+ is the harder acid, being less polarizable than a softer acid. That means it accepts electron density more easily, because it holds onto it more easily (it is less polarizable), and consequently has greater ... WebJan 17, 2016 · H2S is a weak acid. H2S is a Brønsted acid, because it is donating a proton to the water. It is also a Lewis acid, because it is accepting a pair of electrons to form the O-H bond in hydronium ion. H2S has two lone pairs on the S, so it can also act as a Lewis base. In the presence of a strong acid like H2SO4, the H2S becomes protonated.
