I'm supposed to design a scheme to seperate the cations Ca and Pb based on the concept of precipitation and the differences in solubility. I got the first one - adding Cl to a solution of Ag and Cu will cause AgCl to precipitate while Cu remains in solution - but my brain refuses to cooperate with me any further. Anyone willing to offer a jump start?

adding Cl to this one will also do the trick. CaCl is soluble whereas PbCl2 is insoluble (though is slightly soluble in hot water i believe).

This may be the inertia of the Brain.
To relieve this fatigue either change the topic or go for a relaxation by a stroll etc., before resuming your work.

I've got some pencil and paper here. I will draw stick figures and bring coffee. Coffee and my stick men will enlighten your brain.
