# How can I recover PbNO3 from PbI2?

I'm a chemistry school teacher.

I want to know how to recover lead Nitrate from the ppt of PbI2.

I know I can do it using conc HNO3 but I do not know if NO or HI will form. Also I would need a guide on the conditions of the reaction.

I don't want to dispose the lead if I can avoid that.

Thank you
