2Al + 3S = Al2S3
Al2S3 + 6KOH = 2Al(OH)3 + 3K2S
2Al(OH)3 + 3Na2SO4 = Al2(SO4)3 + 6NaOH
Al2(SO4)3 + 6NaOH = 2Al(OH)3 + 3Na2SO4
2Al(OH)3 = Al2O3 + 3H2O
2Al + 3S = Al2S3
Al2S3 + 6KOH = 2Al(OH)3 + 3K2S
2Al(OH)3 + 3Na2SO4 = Al2(SO4)3 + 6NaOH
Al2(SO4)3 + 6NaOH = 2Al(OH)3 + 3Na2SO4
2Al(OH)3 = Al2O3 + 3H2O
