Lead sulfate to carbonate

IG - 24-4-2006 at 10:53

I understand that it is possible to convert lead sulfate by reacting it with a solution of ammonium or sodium carbonate. Does anyone know how fast this reaction proceeds. Does increasing temperature increase the rate significantly?

As I understand it, you're supposed to boil it (making ammonium carbonate a bad choice). Can't help you with rate, though I can certainly tell you it's going to depend on the size of the lead sulfate material.

I have done this reaction to get lead acetate from old batteries. It does work but you have to grind the sulphate and boil it with lots of carbonate. Even then you don't get complete reaction but, if you settle or filter off the carbonate/sulphate mixture and leach it with acetic acid the carbonate disolves and you can repeat the process with the leftover sulphate.
