FeCl3 in water

Why doesn't the Cl- react with water in a reaction involving FeCl3 and water?

Cl- is a spectator ion. Spectator ions exist in the same form on both the reactant and product sides of a chemical reaction. They are present in solutions but don't take part in a solution's chemical reaction. The alkali metals of the first column of the periodic table and the halogen gases from the second to last column of the periodic table are groups of elements that provide spectator ions.
