write a balanced equation for the reaction that occurs when an aqueous solution of iron(II) chloride is mixed with an aqueous solution o potassium hydroxide.

Answer 1

Being as these are in an aqueous solution it brings to mind the pressence of ions.
Im not saying this is correct (it's only a guess) but the potassium could displace iron from the chloride producing Potassium chloride (simple reactivity series of metals) and Solid Iron. The hydroxide could possibly just gain another H to become water.
I don't know if this is the correct answer as i'm only doing my A levels but this is what i think would happen.
Hope you can work out the equation from that.

Answer 2

Bad guess.
FeCl2(aq) + 2KOH(aq) ==> Fe(OH)2(s) + 2KCl(aq)
Fe(OH)2 is insoluble in water solution.
