Answer:

Nitric acid has at least two different reactions with silver, depending on its concentration.

Explanation:

If your concentration of nitric acid is high, it will react with silver accordingly:

#Ag(s)+2HNO_3(aq) rarr 4AgNO_3(aq)+ NO_2(g)+H_2O (l)#

If the concentration of nitric acid is low, then this reaction will take place:

#3Ag(s)+4HNO_3(aq) rarr 3AgNO_3(aq)+NO(g)+2H_2O (l)#

And if you noticed a yellow or brown gas being released, that's the nitrogen dioxide.

The white powder could be either copper or silver nitrate, as both are white solids.
