How can I make FeCl2??

take a lump of iron. chuck it in a bucket of hydrochloric acid. job done.

 

if you want to separate the FeCl2 from the water, either wait for the water to evapourate leaving crystals(they will probably be green due to water in the crystals) or place in an oven to speed up evapouration.

 

to get anhydrous FeCl2 use a dessicator. anhydrous FeCl2 is offwhite and will regain a greenish colour on exporsure to moisture from the air.

Allowing the water to evaporate will not result in formation of FeCl2. The material will be oxidized and at best you'll end up with a mix of hydrated FeCl2 and FeCl3. More likely, you'll end up with a basic ferric chloride.

 

I also doubt whether you can make the anhydrous salt in a dessicator. Many hydrated salts of transition metals tend to loose HCl as well as H2O, leaving behind a basic chloride. Many such salts need drying in an atmosphere of HCl. I'm not sure, however, how strong this effect is for FeCl2.4H2O.

Wait a tick. Wouldn't dissolving a lump of iron under oxic conditions yield FeCl3?

One would either have to start with Fe(II) or use a reducing agent.

But I cant get anywhere HCl.

Is there any other way to make it??

You've probably got some HCl in your house. Check the ingredients on the toilet bowl cleaner.

But wouldn't those other ingredients that are in the cleaner react too??

That's rubbish and no serious chemistry. Use real chemicals! Toilet cleaner may contain some HCl, but it also contains detergents, perfumes, stuff to make it more viscous, coloring agents, et.c Totally useless for any other purpose than cleaning surfaces.

 

HCl in reasonable purity must be available in any hardware store. It also is called muriatic acid. This acid can be somewhat yellow/green, but simple distillation makes pure HCl (dissolved in water), perfectly suitable for experiments.

Iron is a very good reducing agent.

That means another way to get FeCl2 is to start with FeCl3 (used as an etchant) and add iron; steel wool works reasonably well. Use an excess of the iron and then filter it off.

Is there any way to make HCl myself??

Cut open your stomach?

 

Just get some from the store! It's real cheap.

Sure, just vomit.

 

Ha, NeonBlack beat me to it

I don't live in USA. I live in Latvia and don't know any shop that sells HCl.

what do you want FeCl2 for?

There might be a substitute that is easy to get.

I wanted to get FeCl2 to make FeCl3. I want to make a PCB from FeCl3.

that`s easy then use the HCl and add a little H2O2 or chlorate to it and drop the copper plate in there, it`s a Little slow to start but soon takes off quite nicely, and all it needs is Exposure to Air (so don`t do it in a sealed jar). and away you go

 

when it`s exhausted all you need to do is add more HCL or take a few ml of the used liquid and add that to fresh HCl and the reaction keeps on going, no need for the Iron Ion at all this way
