Hi all,
Do I need to make up Iron III Nitrate fresh?
The prac is called "reversible and irreversible reactions", being used with Cobalt Chloride, Potassium Thiocyanate, Mg ribbon, steel wool.
I have some stock solution made up, but who knows when it was made!!
Thanks
Helen

I'm sure it's only Iron (II) nitrate that needs to be made fresh. We've got droppers of Iron (III) nitrate that sit and wait to be used and no issues with it

Re: Iron III Nitrate
I'd be convincing the teachers not to use Cobalt Chloride anymore...or just don't purchase any more. We have removed all Cobalt offsite and it's amazing when you tell them that it is not available to them what interesting ideas they come up with.
Re: Iron III Nitrate
Thanks everyone for your replies!
It went fine using the stock I already had.
