how why does aluminium metal become passive when heated with concentrated hn O3? write the5 strongest acid all over the world? |

Answer» Aluminium reacts VIGOROUSLY with NITRIC acid once the Al2O3 layer has been breached. (HOWEVER, as Kraput pointed out, if the HNO3 is very strong, it will form a passive layer) the reaction is just like magnesium with nitric acid, except that it takes a few minutes to get started. it produces aluminium nitrate and HYDROGEN gas and a lot of heat, as well as NITROGEN oxides fumes. |
