Robert Dennis, I. Potgieter, S. Basson] The kinetics of the oxidation of formaldehyde by octacyanomolybdate(V) ions has been studied in aqueous alkaline medium. A formaldehyde-dependent and -independent reaction has been observed. The HCHO-dependent reaction displays first order kinetics in [Mo(CN)8 3−], [HCHO], [OH−] and alkali metal ion catalysis was observed. The rate law is consistent with: $$ \frac{{ - {\text{d}}[{\text{Mo}}\left( {\text{CN}} \right)_{ 8}^{ 3- } ]}}{\text{dt}} = { 2}K_{\text{h}} K_{ 1} K_{ 2} k_{ 3} \left[ {{\text{Mo}}\left( {\text{CN}} \right)_{ 8}^{ 3- } } \right] \, \left[ {\text{HCHO}} \right] \, \left[ {{\text{OH}}^{ - } } \right] \, \left[ {{\text{A}}^{ + } } \right]. $$ Activation parameters for both the formaldehyde-dependent and -independent reaction have been obtained. The activation parameters for the HCHO-independent reaction provide evidence for the identification of the reaction. A reaction mechanism is proposed.
