Vedclass · Answer

(B) substance shows an increase in weight in a magnetic field if it is paramagnetic (contains unpaired electrons).$A$) $TiO_2$: $Ti^{+4}$ is $3d^0$ (diamagnetic).$B$) $Fe_2(SO_4)_3$: $Fe^{+3}$ is $3d^5$ ($5$ unpaired electrons,paramagnetic).$C$) $KMnO_4$: $Mn^{+7}$ is $3d^0$ (diamagnetic).$D$) $ScCl_3$: $Sc^{+3}$ is $3d^0$ (diamagnetic).Since $Fe_2(SO_4)_3$ is paramagnetic,it will be attracted to the magnetic field,resulting in an apparent increase in weight.

Which of the following will show an increase in weight when kept in a magnetic field?
