Question

Giải hộ nhé đừng thắc mắc:

a) Al → Al₂O₃ → Al(NO₃)₃ → Al(OH)₃ → Na[Al(OH)₄] → Al(OH)₃ → Al₂O₃ → Na[Al(OH)₄] → Al₂(SO₄)₃ → KAl(SO₄)₂.12H₂O

Answer 1

a) Al → Al₂O₃ → Al(NO₃)₃ → Al(OH)₃ → Na[Al(OH)₄] → Al(OH)₃ → Al₂O₃ → Na[Al(OH)₄] → Al₂(SO₄)₃ → KAl(SO₄)₂.12H₂O

4Al+3O2-to>2Al2O3

Al2O3+6HNO3->2Al(NO3)3+3H2O
Al(NO3)2+3NaOH->Al(OH)3+3NaNO3

Al(OH)3+NaOH->Na(Al(OH)4)

Na(Al(OH)4) + NH4Cl → Al(OH)3 + NH3 + NaCl + H2O

2Al(OH)3 -to>Al2O3+3H2O

Al2O3+3H2O+2NaOH->2Na(AlOH)4

2Na(Al(OH)4) + 4H2SO4 → Al2(SO4)3 + Na2SO4 + 8H2O

Al2(SO4)3+24H2O+K2SO4->2KAl(SO4)2.12H2O
