Hello fellow chemists, I have a few question I would really appreciate it if I can get some expert opinions and answers about them.
If a bunch of ions, lets say 4 of them are in a beaker, Na+, Cu2+, Ba2+, Pb2+, and I want to separate one from another by selectively precipitating each. I know I'm suppose to add an negative ion and then filter it but what ion am I going to add in? And one of them will remain soluble in the solution after I do so.
Also I have another uestion regarding precipitate.
Lets say LiCl and Na3PO4 were mixed and a precipitate formed. How is this possible? LiPO4 is soluble and NaCl is also soluble.
