    Aluminum triangle. 1) 2al + 2naoh + 2h2o === 2naalo2 + 3h2o

    2) 4Al+3O2 === 2Al2O3 (Condition: Ignite).

    2Al+Fe2O3 === Al2O3 + 2Fe(Condition: High Temperature)].

    3) 2Al2O3 === 4Al + 3O2 (rising) (Condition: Electrolysis).

    4) 2Al+3Cl2 === 2AlCl3 (Condition: Ignite).

    2Al + 6HCl === 2ALCL3 + 3H2 (rising)].

    5) al2o3 + 2naoh === 2naalo2 + h2o

    6) al2o3 + 6hcl === 2alcl3 + 3h2o

    7) Naalo2 + HCl + H2O === NaCl + Al(OH)3 (precipitate).

    8) al(oh)3 + naoh === naalo2 + 2h2o

    9) 2Al(OH)3 === Al2O3 + 3H2O(Condition: Heating).

    10)al(oh)3 + 3hcl === alcl3 + 3h2o

    11) AlCl3 + === Al(OH)3 (precipitate) +3NH4Cl

    AlCl3 + 3NaOH === Al(OH)3 (precipitate) +3NaCl].

    12) Naalo2 + HCl(over) === ALCL3 + NaOH + H2O

    Ionic Equation:

    1 al3+ +3oh- = al(oh)3 (s)

    2 al(oh)3 + 3h+ = al3+ +3h2o

    3 al(oh)3 + oh- = alo2- +2h2o

    4 alo2- +h+ +h2o = al(oh)3 (s)

    5 al3+ +4oh- = alo2- +2h2o

    6 AlO2-+ 4H+ = Al3+ +2H2O s is the precipitation.

    Iron Triangle. 1 fe + 2h+ = fe2+ +h2 (g)

    2 fe2+ +zn = fe + zn2+

    3 2fe2+ +cl2 = 2fe3+ +2cl-

    4 2Fe3+ +Fe = 3Fe2+ can also react with Cu.

    5 2fe + 3cl2 = 2fe3+ +6cl-

    6 2fe3+ +3zn = 2fe + 3zn2+
