Question

When KOH(aq) is added to the solution, will the solubility of Ni(OH)₂ increase, decrease, or remain the same? Give the balanced net ionic equation for the dissolution process. [Hint: Refer to complex ions formations]

Accepted Answer

This solubility of Ni(OH)₂(s) will decrease.
Net ionic equation: Ni(OH)₂(s) ⇌ N²⁺(aq) + 2 OH^–(aq)

Answer

This solubility of Ni(OH)₂(s) will increase.
Net ionic equation: Ni(OH)₂(s) + 4 OH^–(aq) ⇌ Ni(OH)₆^4–(aq)

Answer

This solubility of Ni(OH)₂(s) will increase.
Net ionic equation: Ni²⁺(aq) + 6 OH^–(aq) ⇌ Ni(OH)₆^4–(aq)
