Write the reaction equations according to the transformation scheme: aluminum → aluminum oxide → aluminum nitrate → aluminum hydroxide → aluminum oxide
1) 2Al + 3O2 = 2Al2O3
2) Al2O3 + 6HNO3 = 2Al (NO3) 3 + 3H2O
3) Al (NO3) 3 + 3NaOH = Al (OH) 3 + 3NaNO3
5) 2Al (OH) 3 = Al2O3 + 3H2O (the reaction takes place upon ignition, you must write t above the “equals”)
