Dear,

I have prepared Lead Nitrate by putting Lead pieces in solution of Nitric Acid. Everything goes fine. Issue is, preparation process is too much slow. Even I put that on fire but heat did not effect as I was assuming it would be. It consumes a lot of time. Could any one please help me out to declare any catalyst or any other method to quicken the preparation?

Regards,
