Chapter 4, Problem 4KSP

When steel wool $\left[\text{Fe}\left(\text{s}\right)\right]$ is placed in a solution of ${\text{CuSO}}_{\text{4}}\left(\text{aq}\right)\text{,}$ the steel becomes coated with copper metal and the characteristic blue color of the solution fades. What is the net ionic equation for this reaction?

(a)

$\text{Fe}\left(s\right)+{\text{CuSO}}_4\left(aq\right)\to {\text{FeSO}}_4\left(aq\right)+\text{Cu}\left(s\right)$

(b)

$\text{Fe}\left(s\right)+\text{Cu}\left(aq\right)\to \text{Fe}\left(aq\right)+\text{Cu}\left(s\right)$

(c)

${\text{FeSO}}_{\text{4}}\left(aq\right)+\text{Cu}\left(s\right)\to \text{Fe}\left(s\right)+{\text{CuSO}}_{\text{4}}\left(aq\right)$

(d)

$\text{Fe}\left(s\right)+{\text{Cu}}^{\text{2+}}\left(aq\right)\to {\text{Fe}}^{\text{2+}}\left(aq\right)+\text{Cu}\left(s\right)$

(e)

$\text{Fe}\left(s\right)+\text{Cu}\left(aq\right)\to \text{Fe}\left(aq\right)+\text{Cu}\left(s\right)$
