Problem 4.112 Use the activity series of metals (the table below) to predict the outcome of each of the following reactions. If no reaction occurs, answer noreaction. Part A Na^+ (aq) + Zn(s) ? > ? Express your answer as a chemical equation. Identify all of the phases in your answer. Enter noreaction if no reaction occurs. Part B HCl(aq) + Pt(s) -- > ? Express your answer as a chemical equation. Identify all of the phases in your answer. Enter noreaction if no reaction occurs.

Explanation / Answer

part A)

Na+ (aq) + Zn (s) --------------------------> no reaction

part B)

HCl (aq) + Pt (s) -------------------->no reaction

explanation:

(a) Na reduction potential is lessre than Zn reduction potential . so Na can reduce Zn+2 but Zn cannot reduce Na+

2 Na + Zn+2 ----------------------> 2 Na+ + Zn (it is possible)

(b) Pt is below to H2 electrode. so it can replace H2 form HCl.
