Aqueous solutions of potassium hydroxide and iron(II) chloride react in a precipitation reaction to form insoluble iron(II) hydroxide. 2KOH(aq)+FeCl2(aq)⟶2KCl(aq)+Fe(OH)2(s)

Answer 1

what's the question?

Split up aq strong electrolytes: soluble salts, strong bases, strong acids.

KOH strong base

FeCl2(aq) and KCl(aq) both soluble salts.

2KOH(aq)+FeCl2(aq)⟶2KCl(aq)+Fe(OH)2(s)

Full ionic:

2K+ + 2OH- + Fe2+ + 2Cl- --> 2K+ + 2Cl- +Fe(OH)2

Net ionic: cross out spectators

Fe2+ + 2OH- --> Fe(OH)2
