Осуществите превращения NaCl - HCl - FeCl2 - FeCl3 - HCl - H2 - HBr - AlBr3 - Br2

Question

Осуществите превращения
NaCl - HCl - FeCl2 - FeCl3 - HCl - H2 - HBr - AlBr3 - Br2

Answer 1

2NaCl+H2SO4->Na2SO4+2HCl
2HCl+Fe-> FeCl2+H2
2FeCl2+Cl2->2FeCl3
FeCl3+3HOH->Fe(OH)3+3HCl
2HCL-t->H2+Cl2
H2+Br2->2HBr
3HBr+AlCl3-> 3HCl+ AlBr3(?)
2AlBr3-> 2Al +3Br2
