What is the shape of the permanganate ion ($MnO_4^−$) ?

What is the oxidation state of manganese in $KMnO_4$?

According to VSEPR theory, what is the predicted molecular geometry of the $MnO_4^{2-}$ (manganate) ion?

Identify the ion with a $3d^n$ configuration (where n > 0 and n < 10) that is also paramagnetic.

${\rm{KMn}}{{\rm{O}}_4}$ in basic medium is used as

Wrong match is

Which one of the following does not decolourise an acidified ${\rm{KMn}}{{\rm{O}}_4}$ solution?

Which of the following is NOT a possible oxidation state of Mn in a compound formed by the reduction of $KMnO_4$ in acidic medium?

The manganate ($MnO_4^{2-}$) and permanganate ($MnO_4^{-}$) ions are tetrahedral. This tetrahedral geometry is primarily due to:

The color of $KMnO_4$ solution is due to:
