${\mathrm{Fe}}^{+3}+{\mathrm{CH}}_3{\mathrm{COO}}^{-}($excess $)\to {\left[{\mathrm{Fe}}_3{\left({\mathrm{OH}}^{-}\right)}_2{\left({\mathrm{CH}}_3{\mathrm{COO}}^{-}\right)}_6\right]}^{+}\underset{\Delta }{\overset{{\mathrm{H}}_2\mathrm{O}}{\to }}\mathrm{Fe}(\mathrm{OH}{)}_3($ Brown ppt $)+{\mathrm{CH}}_3\mathrm{COOH}+{\mathrm{H}}^{+}$

${\mathrm{Fe}}^{+3}\Rightarrow [\mathrm{Ar}{]}^{18}3{\mathrm{d}}^{5}4{\mathrm{s}}^0$

$\mu =\sqrt{\mathrm{n}(\mathrm{n}+2)}$ BM where $\mathrm{n}=5$

$\mu =\sqrt{35}\mathrm{BM}=5.92\mathrm{BM}$
