The silver deposited can be scraped off and refined again by electrolysis in silver nitrate solution (pure silver rod as cathode and the silver from above process as anode apply voltage of 12 V and current of 200 mA). The silver obtained is 99% pure. 2)metal displacement:- In this the solution is treated with iron wool or zinc dust (recommended).

Sodium nitrate doesn't even make powerful bombs since the sodium ion has a relatively strong bond to the nitrate ion compared to the other alkali metals. If you really needed to, you could distill your own HCl. Muriatic acid will always be available since it is used to clean concrete and adjust the pH of swimming pools. It's just too useful.
