Manganese(II) Chloride

[jordehwa]

So i want to make some Manganese(II) Chloride From MnO2 and HCL, yes I realize that this makes chlorine.

 

So i dissolved the MnO2 in the hcl and it has green Iron impurities in it, to much for recrystalaltion to work. what would be the best way to get the impurities out?

[Arthur Dent]

My recommendation would be to wash the MnO2 with some diluted acetic acid, which will clean off some of the other metal impurities, wash it again with plenty of distilled water, then one last wash with dilute HCl (iron impurities will react with the Cl along with very little Manganese, leaving the unreacted MnO2 nearly free of iron).

 

Then you'll be ready for the big mean MnO2/conc. HCl reaction. Do this outside or in a fume hood, mucho Cl comes out of that reaction.

FeCl3 can be extracted from solutions in conc HCl with ether.

 

Arthur, note the use of the past tense as in " i dissolved the MnO2". This makes it a bit tricky to wash.

Well i still have more MnO2 Just not very much only 2.50 grams this is just a test experiment.

 

Thanks a lot guys I will let you know how it goes.

Oops, Didn't notice that. Sorry!

 

My knowledge of removing impurities in Manganese salts is limited to the removal of solubles from insolubles. Ferric and Manganese chlorides would look to me as pretty hard to separate from one another...

Here is good!
