Question

Write out the chemical equation describing the dissolution of solid K₄[Fe(CN)₆] in water. Include states of matter. You do not need to include H₂O(l) in your equation.

Answer 1

The dissolution of solid K4[Fe(CN)6] in water is represented by the chemical equation K4[Fe(CN)6](s) → 4K+(aq) + [Fe(CN)6]4-(aq), suggesting the solid dissociates into potassium and ferrocyanide ions in aqueous solution.

Step-by-step explanation:

The chemical equation describing the dissolution of solid potassium ferrocyanide (K₄[Fe(CN)₆]) in water is:

K₄[Fe(CN)₆](s) → 4K+(aq) + [Fe(CN)₆]4-(aq)

This equation indicates that when potassium ferrocyanide dissolves in water, the solid separates into potassium ions (K+) and the ferrocyanide complex ion ([Fe(CN)₆]4-).

Both ions are in aqueous (aq) state, indicating that they are dissolved in water. This dissociation is a physical change that demonstrates one of the fundamental properties of ionic compounds when they interact with polar solvents like water.
