Question 134

When solid copper(II) carbonate is added to dilute nitric acid, a reaction occurs to form copper(II) nitrate solution, liquid water, and carbon dioxide gas.

The equation for the reaction is:

CuCO3(.....)+2HNO3(aq)→Cu(NO3)2(.....)+H2O(l)+CO2(g) \text{CuCO}_3(\text{.....}) + 2\text{HNO}_3(\text{aq}) \rightarrow \text{Cu(NO}_3)_2(\text{.....}) + \text{H}_2\text{O}(\text{l}) + \text{CO}_2(\text{g}) CuCO3​(.....)+2HNO3​(aq)→Cu(NO3​)2​(.....)+H2​O(l)+CO2​(g)
