Question

Explain what happens when following reaction takes place and give
the balanced chemical equation :
Copper reacts with concentrated Nitric acid.​

Answer 1

Answer:

4 HNO3(l) + Cu(s) ==> Cu(NO3)2(s and aq) + 2 NO2(g) + 2 H2O(l)

Explanation:

The copper nitrate salt that forms is a deep blue color. The nitrogen dioxide is a maroon vapor. Place the copper disk in the bottom of the glass cylinder.

Answer 2

Answer:

Nitric acid reacts with copper according to the reaction: ... 4 HNO3(l) + Cu(s) ==> Cu(NO3)2(s and aq) + 2 NO2(g) + 2 H2O(l) The copper nitrate salt that forms is a deep blue color. The nitrogen dioxide is a maroon vapor.

Explanation:

Balanced equation:

4HNO3(l) + Cu(s)--->Cu(NO3)2(aq)+2NO2(g)+2H20(l)
