Question

The following chemical reaction takes place in aqueous solution: 

Fe(NO3)2(aq)+3 KOH(aq) → Fe(OH)3(s)+3 KNO3(aq) 

Write the net ionic equation for this reaction.

Answer 1

we have below given equation
Fe(NO3)3 (aq) + 3 KOH (aq) --> Fe(OH)3 (s) + 3 KNO3 (aq)




Total ionic equation is
Spectator ions should not be removed here. Spectator ions are part of total ionic equation
Fe3+ (aq) + 3 NO3- (aq) + 3 K+ (aq) + 3 OH- (aq) --> Fe(OH)3 (s) + 3 K+ (aq) + 3 NO3- (aq)

Spectator ions should be removed now. Spectator ions are not part of total ionic equation
After removing Spectator ions, net ionic equation is:
Fe3+ (aq) + 3 OH- (aq) —> Fe(OH)3 (s)

Answer:
Fe³⁺ (aq) + 3 OH^- (aq) —> Fe(OH)₃ (s)
