Question

reaction of Cooper with nitric acid​

Answer 1

Explanation:

Copper and Nitric Acid. ... 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.

Answer 2

Answer:

Copper and Nitric Acid. ... 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

In dilute nitric acid, the reaction produces nitric oxide, NO, instead: 3Cu(s) ... A Historical Sidelight: Ira Remsen on Copper and Nitric Acid.
