Question

White a balance chemical equation :

Action of cold and dilute nitric acid on copper. ​

Answer 1

Explanation:

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

Heya!!

Copper reacts with cold and dilute nitric acid to form copper nitrate, water and nitric oxide.

3Cu + 8HNO3 --------------> 3Cu(NO3)2 + 4H2O + 2NO⬆️

Copper + Nitric acid Copper nitrate + water + Nitric oxide

Thanks.
