(a)
Predict whether a single replacement reaction will or will not occur for the reaction
Zn + Fe ( NO 3 ) 2 ( aq ) → Fe + Zn ( NO 3 ) 2 ( aq )
.
(a)

Answer to Problem 14E
Explanation of Solution
Given Info: Refer to table 13.5 in the textbook.
Explanation:
Activity series is a list in which metals are placed according to their activity. The metals that are placed higher in the activity series have more tendency to lose electrons and are more active. The metals that are higher in the activity series replaces the metals that are placed lower to it from their aqueous solution. The
The activity series indicate that zinc is more active than iron and thus zinc metal replaces iron from its aqueous solution. The single replacement reaction will occur for the given reaction.
Conclusion:
Therefore, the single replacement reaction will occur for the reaction,
(b)
Predict whether a single replacement reaction will or will not occur for the reaction
Pb + FeCl 2 ( aq ) → Fe + PbCl 2 ( aq )
