Testing for Fe(II) Lab

I'm trying to create a lab that tests for Fe (II) in solution. We're supposed to make a 'control' set for the experiment by creating FeCl2 from FeCl3 and testing to see if the indicator we selected worked.

 

i have several questions:

 

does anyone know a good way to go from FeCl3 to FeCl2? Its .002 M FeCl3 and I think we have all standard chemicals available.

 

can anyone help me find a way to test if there is actually Fe(II) in the solution? I'm just so lost right now... any help would be appreciated!

the tests for Iron is pretty simple, you only need a basic soln such as Ammonia or sodium hydroxide.

add either of these to the soln you want to test.

Fe2+ will give a pale Green ppt

Fe3+ will give a red/brown ppt.

 

the rest is up to you to either Research or Experiment, but now that you have a way to test it, I`m sure you`ll be able to work out the rest :)
