Question

The number of ions that will be produced when potassium ferrocyanide,

K4[Fe(CN)6], dissolves in water is _________. This shows that
__________ is the ligand in the coordination compound.

Answer 1

Five ions are produced when potassium ferrocyanide dissolves in water: four potassium ions and one ferrocyanide ion, which shows that cyanide is the ligand in the coordination compound.

Step-by-step explanation:

The number of ions produced when potassium ferrocyanide, K4[Fe(CN)6], dissolves in water is five. When potassium ferrocyanide dissolves, it dissociates into four potassium ions (4K+) and one ferrocyanide ion ([Fe(CN)6]4-). This shows that cyanide (CN-) is the ligand in the coordination compound as it is bonded to the central iron ion within the ferrocyanide anion.

The stability of the ferrocyanide ion is indicated by a very large formation constant (Kf) which is equal to 1 × 1035. However, since the ferrocyanide complex is so stable, the concentration of free cyanide ions in equilibrium with a 0.65 M solution of K4[Fe(CN)6] will be very small and can be considered negligible without doing complex calculations.

Answer 2

When potassium ferrocyanide, K4[Fe(CN)6], dissolves in water, it dissociates into its respective ions.

When potassium ferrocyanide, K4[Fe(CN)6], dissolves in water, it dissociates into its respective ions.The dissociation reaction for K4[Fe(CN)6] in water is as follows:

When potassium ferrocyanide, K4[Fe(CN)6], dissolves in water, it dissociates into its respective ions.The dissociation reaction for K4[Fe(CN)6] in water is as follows:K4[Fe(CN)6] → 4K+ + [Fe(CN)6]4-

When potassium ferrocyanide, K4[Fe(CN)6], dissolves in water, it dissociates into its respective ions.The dissociation reaction for K4[Fe(CN)6] in water is as follows:K4[Fe(CN)6] → 4K+ + [Fe(CN)6]4-So, the number of ions produced when potassium ferrocyanide dissolves in water is 5. Four potassium ions (K+) and one hexacyanoferrate(II) ion ([Fe(CN)6]4-) are formed.

Four potassium ions (K+) and one hexacyanoferrate(II) ion ([Fe(CN)6]4-) are formed.The ligand in the coordination compound K4[Fe(CN)6] is the hexacyanoferrate(II) ion ([Fe(CN)6]4-). It acts as a ligand by donating six cyanide (CN-) ions to the central iron (Fe) atom, forming a complex ion.
