In nitroprusside ion, the iron exists as $Fe^{2+}$ and $NO$ as $NO^+$ rather than $Fe^{3+}$ and $NO$ respectively. These forms of ions are established with the help of
magnetic moment in solid state
thermal decomposition method
by reaction with $KCN$
by action with $K_2SO_4$
Why do the transition elements exhibit higher enthalpies of atomisation?
Copper displaces which of the metal from their salt solutions
Which of the following is not correct about transition metals
The catalytic activity of transition metals and their compounds is ascribed mainly to
How would you account for the following:
$(i)$ of the $d^{4}$ species, $Cr ^{2+}$ is strongly reducing while manganese $(III)$ is strongly oxidising.
$(ii)$ Cobalt $(II)$ is stable in aqueous solution but in the presence of complexing reagents it is easily oxidised.
$(iii)$ The $d^{1}$ configuration is very unstable in ions.
