Chapter 13, Problem 14E

(a)

To determine

Predict whether a single replacement reaction will or will not occur for the reaction $\text{Zn}+\text{Fe}{\left({\text{NO}}_{\text{3}}\right)}_{\text{2}}\left(\text{aq}\right)\to \text{Fe}+\text{Zn}{\left({\text{NO}}_{\text{3}}\right)}_{\text{2}}\left(\text{aq}\right)$.

Answer to Problem 14E

The single replacement reaction will occur for the reaction,

$\text{Zn}+\text{Fe}{\left({\text{NO}}_{\text{3}}\right)}_{\text{2}}\left(\text{aq}\right)\to \text{Fe}+\text{Zn}{\left({\text{NO}}_{\text{3}}\right)}_{\text{2}}\left(\text{aq}\right)$

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 chemical reaction is,

$\text{Zn}+\text{Fe}{\left({\text{NO}}_{\text{3}}\right)}_{\text{2}}\left(\text{aq}\right)\to \text{Fe}+\text{Zn}{\left({\text{NO}}_{\text{3}}\right)}_{\text{2}}\left(\text{aq}\right)$

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,

$\text{Zn}+\text{Fe}{\left({\text{NO}}_{\text{3}}\right)}_{\text{2}}\left(\text{aq}\right)\to \text{Fe}+\text{Zn}{\left({\text{NO}}_{\text{3}}\right)}_{\text{2}}\left(\text{aq}\right)$

(b)

To determine

Predict whether a single replacement reaction will or will not occur for the reaction $\text{Pb}+{\text{FeCl}}_{\text{2}}\left(\text{aq}\right)\to \text{Fe}+{\text{PbCl}}_{\text{2}}\left(\text{aq}\right)$

Answer to Problem 14E

The single replacement reaction will not occur for the reaction,

$\text{Pb}+{\text{FeCl}}_{\text{2}}\left(\text{aq}\right)\to \text{Fe}+{\text{PbCl}}_{\text{2}}\left(\text{aq}\right)$

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 chemical reaction is,

$\text{Pb}+{\text{FeCl}}_{\text{2}}\left(\text{aq}\right)\to \text{Fe}+{\text{PbCl}}_{\text{2}}\left(\text{aq}\right)$

The activity series indicate that lead is less active than iron and thus lead metal will not be able to replace iron from its aqueous solution. The single replacement reaction will not occur for the given reaction.

Conclusion:

Therefore, the single replacement reaction will not occur for the reaction,

$\text{Pb}+{\text{FeCl}}_{\text{2}}\left(\text{aq}\right)\to \text{Fe}+{\text{PbCl}}_{\text{2}}\left(\text{aq}\right)$

(c)

To determine

Predict whether a single replacement reaction will or will not occur for the reaction $\text{2Ag}+{\text{2HNO}}_3\left(\text{aq}\right)\to {\text{H}}_2+{\text{2AgNO}}_3\left(\text{aq}\right)$

Answer to Problem 14E

The single replacement reaction will not occur for the reaction,

$\text{2Ag}+{\text{2HNO}}_3\left(\text{aq}\right)\to {\text{H}}_2+{\text{2AgNO}}_3\left(\text{aq}\right)$

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 chemical reaction is,

$\text{2Ag}+{\text{2HNO}}_3\left(\text{aq}\right)\to {\text{H}}_2+{\text{2AgNO}}_3\left(\text{aq}\right)$

The activity series indicate that silver is less active than hydrogen and thus silver metal will not be able to replace hydrogen from its aqueous solution. The single replacement reaction will not occur for the given reaction.

Conclusion:

Therefore, the single replacement reaction will not occur for the reaction,

$\text{2Ag}+{\text{2HNO}}_3\left(\text{aq}\right)\to {\text{H}}_2+{\text{2AgNO}}_3\left(\text{aq}\right)$
