Answer 2

Chemical Transformation Chain: Fe - FeCl2 - Fe(OH)2 - Fe3(PO4)3

To achieve the transformation chain from Fe to Fe3(PO4)3, we can follow the series of chemical reactions based on the provided information.

1. Fe to FeCl2: - Fe + 2HCl → FeCl2 + H2 - Fe + 2HCl → FeCl2 + H2

2. FeCl2 to Fe(OH)2: - FeCl2 + 4NH4OH → Fe(OH)2 + 2NH4Cl - FeCl2 + 4NH4OH → Fe(OH)2 + 2NH4Cl

3. Fe(OH)2 to Fe3(PO4)3: - 2Fe(OH)2 + 2H3PO4 → Fe3(PO4)3 + 6H2O - 2Fe(OH)2 + 2H3PO4 → Fe3(PO4)3 + 6H2O

Therefore, the complete transformation chain from Fe to Fe3(PO4)3 is as follows: Fe + 2HCl → FeCl2 + H2 FeCl2 + 4NH4OH → Fe(OH)2 + 2NH4Cl 2Fe(OH)2 + 2H3PO4 → Fe3(PO4)3 + 6H2O
