Any metal salt will work, but i dont know if the H will replace the Na, because i think it is higher up on the reactivity series of single replacement reactions. If it did it would create HNO3 and NaOH, which actually could be useful. Just stick with NaOH, because its easy to find and doesnt decompose.
