Ferrous (Fe^+2) salt reacts with potassium  ferricyanide  to form a blue precipitate which is called Turnbull's blue. The reaction is as...

Prussian blue is formed when ferric(Fe^3) salt reacts with  ferrocyanide.  Here we see both oxidation states of iron but only +2 oxidation s...

As the lobes of  d x^ 2 − y^ 2  point towards the ligands , this orbital has highest energy . The lobes of  d x y  orbital lie between the l...
