Question

a strip of copper is immersed in dilute nitric acid. What happens to the pH of this solution as the reaction proceeds?

Answer 1

Here's the reaction that occurs:\[3{\rm Cu}(s) + 8 {\rm H}^+(aq) + 2 {\rm NO}_3^-(aq) \rightarrow 3{\rm Cu}^{2+}(aq) + 2 {\rm NO}(g) + 4 {\rm H}_2{\rm O}(l)\]What do you think this reaction will do to [H+]?
