Question

Exercise 18.59: Problems by Topic-Voltaic Cells, Standard Cell Potentials, and Direction of Spontaneity Decide whether or not each of the following metals dissolves in 1 M HNO_3. For those metals that do dissolve, write a balanced redox reaction showing what happens when the metal dissolves. Cu Express your answer as a chemical equation. Enter noreaction if there is no reaction. Identify all of the phases in your answer. Au Express your answer as a chemical equation. Enter noreaction if there is no reaction. Identify all of the phases in your answer.

Explanation / Answer

the correction in the reaction follows as:

Cu(s)  + 4HNO3(l)    Cu(NO3)2(aq)   + 4NO(g) + 2H2O(l)
