What will happen to the solubility of Fe(OH)₃ when KCN(aq) is added to the solution? Provide the balanced net ionic equation for the dissolution process. [Hint: Refer to complex ions formations]

• A. This solubility of Fe(OH)₃ will increase.
  Net ionic equation: Fe³⁺(aq) + 6 CN^–(aq) ⇌ Fe(CN)₆^3–(aq) + 3 OH^–(aq)
• B. This solubility of Fe(OH)₃ will increase.
  Net ionic equation: Fe(OH)₃(s) + 6 CN^–(aq) ⇌ Fe(CN)₆^3–(aq) + 3 OH^–(aq)
• C. This solubility of Fe(OH)₃ will decrease.
  Net ionic equation: Fe(OH)₃(s) ⇌ Fe³⁺(aq) + 3 OH^–(aq)

Answer: (B)
