Bronze + Nitric acid = ???


anthropos

Recommended Posts

When bronze is completely dissolved in nitric acid, what colour would the solution be?

 

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?

 

Thanks, guys!

The thing is, neither copper nor tin will react in your nitric acid. It's to do with the nitrate anion's complexing abilities. And so its size.

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.
