Bronze + Nitric acid = ???

Is it light blue, because after the reaction, lead (II) nitrate and copper (II) nitrate are formed (I SUPPOSE). As the former is white and the latter is blue, is it light-blue? o_0
Then name one chemical and describe the test that could be used to determine the presence of copper and tin in solution E.
Um...for this question, I am clueless! Does tests which work on solid tin and copper work on aqueous ones?

If however you manage it.
For the copper, you can add excess ammonia solution and you'll get a dark blue solution.
Where do you get the lead from? Test for lead nitrate, hmmm if i remember rightly (sorry long time now) gives a yellow ppte with excess ammonia which does not dissolve.
No test for tin that i can think of.

Copper reacts with concentrated nitric acid to form a bluish-green solution.
However, in this website, it claims that when nitric acid reacts with bronze, the colour will be green. o_0 so I am rather puzzled.
