[SOLVED] Removing Pb from water
Could anyone get me going with this?
Ksp=[Pb2+][Cl-]^2 by definition.
You are given the KSP and Pb2+ values, simply find the concentration of Cl-. You will notice that you will need a LOT of salt to do this, and creating highly saline environments in water sources kills a lot of plants and wildlife.
Wow, so it is that easy. Thank you very much gravenewworld!
Ok, however don't do it with hot water, or you'll kill people (PbCl2 is quite soluble in hot water).
Furthermore, precipitating Pb with Cl- obviously take in solution the anion and this one can be not appropriate itself for a drinking water: NO3- for example.
This sounds more like Chemistry 101 homework than somebody with bad well water. But, you never know.
