It neutralizes the acid, yielding a salt:[9], In bases, it acts as a Lewis acid by binding hydroxide ions:[9]. The dendritic cells pick up the antigen, carry it to lymph nodes, and stimulate T cells and B cells. Aluminium hydroxide In acid, it acts as a Brønsted–Lowry base. Aluminum + Sodium Hydroxide + Water = Sodium Aluminate + Dihydrogen . A Lewis acid is a species which can bond by accepting a lone pair of electrons.Metal cations behave as Lewis acids when they form coordinate bonds with ligands. It was historically stored in lagoons; this led to the Ajka alumina plant accident in 2010 in Hungary, where a dam bursting led to the drowning of nine people. Start studying [Al(H2O)6]3+ Reaction with OH-. [Co(H2O)6]2+ pink [Cu(H2O)6]2+ blue [Ag(H2O)2]+ colourless NaOH(aq) (dilute) Active species.
