Answer #1

Nickel(II) iodide react with KOH to form Nickel (II) hydroxide and potassium iodide.

Balanced ionic equation for the given reaction is

NiI2(aq) + 2KOH (aq) ------------> Ni(OH)2(s) + 2KI (aq)

Ni(OH)2 has slight solubility in the water therefore it will precipitate in the aqueous solution.
