Lead Nitrate to Lead Chloride
Hi,
I need Lead Chloride (not reagent grade, but with the less contamination as possible)
As the lead I have came from a fishing plumb and I know that it has a lot of tin, I disolved in Nitric acid. (to remove the tin - see this procees
somewhere in the forum)
Currently is digesting, but in the end I will have Lead II nitrate and want to convert to Lead II Chloride.
The first though was to treat it with HCL, but then I found that it can also be precipitated with a NaCl Solution.
Pb(NO3)2(aq) + 2NaCl(aq) → PbCl2(aq) + 2NaNO3(aq)
but then how I separte PbCl2(aq) from NaNO3(aq).
from a web page it states that PbCl2 will precipitate, but why it states (aq) and not (s)?
Solubilty of PbCl2(aq) is very low (1gr/100ml) and NaNO3 is very high 92,1 g/100 ml, so precipitation at low temperatures is possible.
or maybe there is another route.
In the end I need solid PbCl2.
Thanks
Go SAFE, because stupidity and bad Luck exist.

It should be listed as a solid. Just make sure your solution is as cold as possible, and remember that some of your lead will stay in solution.
Please remember: "Filtrate" is not a verb.
Write up your lab reports the way your instructor wants them, not the way your ex-instructor wants them.
