|
Cu 2+ Al 3+ Fe 2+ Fe 3+ |
Cu 2+ often pale blue Al 3+ colourless Fe 2+ green Fe 3+ yellow brown (violet solid) |
|
|
Bronsted-Lowry acid and base |
H+ or OH- |
|
|
Lewis acid and base |
Electron pair acceptor or donor |
|
|
Chelate effect |
Entropy maximized. Multidentate ligands will prioritise over mono and bidentate |
|
|
Shape of complexes |
Linear tollens reagant [Ag(NH3)2] 2+ Tetrahedral CuCl4 2- Square planar cisplatin PtCl2(NH3)2 Octahedral |
|
|
3+ and 2+ Complex ions with CO3 2- |
2+ : Undergoes ligand substitution FeCO3 3+ : CO3 2- acts as a base. Fe3+ acts an acid. It is more acidic as it's charge is higher. It is like a carbonate + acid. Fe(H2O)3(OH)3 + CO2 + H2O Salt + carbon dioxide + water |
|
|
Aluminium special properties |
Excess hydroxide Al(H2O)3(OH)3 ---> [Al(H2O)2(OH)4]- Stronger acid: ---> [Al(H2O)6] 3+ it goes back |
|
|
Exception between NH3 and copper compex |
Generally NH3 replaces all other ligands. Cu(OH)2(H2O)4---> Cu(NH3)4(H2O)2 Cu only replaces 4 |
