Question

.  Осуществите цепочку превращений:

                         а) AI         AI2O3          AI(OH)3        AI2(SO4)3         AICI3

                         б) H2           HBr            NaBr            CaBr2              Ca(OH)2

Answer 1

а)2 Al+3O2 = Al2O3 
Al2O3+ 3Na(OH) = 2Al(OH)3 + 3Na2O 
2Al(OH)3+3K2SO4= 6K(OH)+Al2(SO4)3 
Al2(SO4)3 + 6NaCl= 2AlCl3+ 3Na2SO4

Answer 2

NaBr+Ca(SO4)=CaBr2+Na2(SO4)

Answer 3
