Which of the following statements is incorrect regarding the reaction ?
${\mathrm{CH}}_3\mathrm{CHO}+{\left[\mathrm{Ag}{\left({\mathrm{NH}}_3\right)}_2\right]}^{\oplus }+\mathrm{OH}⟶{\mathrm{CH}}_3{\mathrm{COO}}^{-}+\mathrm{Ag}$

CH₃CHO is an oxidizing agent which reduces Ag from +1 to zero oxidation state, which results in the formation of a grey ppt (or silver mirror like appearance on the wall of test tube).
