2Al + 3S = Al2S3 ( алюминий, сера, сульфид алюминия)
Al2S3 + 6NaOH =2 Al(OH)3 +3 Na2S
2Al(OH)3 +3 H2SO4 = Al2(SO4)3 +6 H2O
2Al(OH)3 + 6H(+) + 3SO4(-2) = 2Al(+3) + 3SO4(-2) + 6H2O
2Al(OH)3 + 6H(+) = 2Al(+3) + 6H2O
Al2(SO4)3 + 3CaCl2 = 2AlCl3 + 3CaSO4
2Al(+3) +3SO4(-2) + 3Ca(+2) + 6Cl(-) = 2Al(+3) + 6Cl(-) + 3CaSO4
3Ca(+2) + 3SO4(-2) = 3CaSO4
AlCl3 + 3NaOH = Al(OH)3 + 3NaCl
Al(+3) + 3Cl(-) + 3Na(+) + 3OH(-) = Al(OH)3 + 3Na(+) + 3Cl(-)
Al(+3) + 3OH(-) = Al(OH)3
