AlCl3 + 3NaOH = Al(OH)3 + 3NaCl

Al(OH)3 + NaOH = Na[Al(OH)4]

2Na[Al(OH)4] + 4H2SO4 = Al2(SO4)3 + Na2SO4 + 8H2O

Al2(SO4)3 + 3CaCl2 = 3CaSO4 + 2AlCl3

Verified answer

2Al+3Cl2=2AlCl3

AlCl3+3NaOH=Al(OH)3+3NaCl

Al(OH)3 + NaOH = Na[Al(OH)4]

2Na[Al(OH)4] + 4H2SO4 =Na2SO4 + Al2(SO4)3 + 8H2O

Al2(SO4)3 + 3BaCl2 = 2AlCl3 + 3BaSO4
