Does a reaction occur when aqueous solutions of iron(II) chloride and barium hydroxide are combined?

Answer 1

Iron(II) chloride is FeCl₂

Barium hydroxide is Ba(OH)₂

They react in a double replacement reaction as follows:

FeCl₂(aq) + Ba(OH)₂(aq) ==> Fe(OH)₂(s) + BaCl₂(aq)

The reason a reaction takes place is because of the formation of a precipitate, Fe(OH)₂
