Explanation / Answer

The molecular equation is

CaI2(aq) + 2 KOH (aq) --------------> Ca(OH)2 (s) + 2KI (aq)

Ca(OH)2 calcium hydroxide is the sparingly soluble salt that precipitates.

The ionic reaction is

Ca+2(aq) +2I- (aq) + 2K+ (aq)+ 2 OH- (aq) -----------------> Ca(OH)2 (s)+2I- (aq) + 2K+ (aq)

The net ionic equation is the ionic equation from which the spectator ions are removed.

The net ionic equation is

Ca+2(aq) + 2 OH- (aq) -----------------> Ca(OH)2 (s)
