Role of MnSO4 in permanganometric titration
Both the oxidating ion $\ce{MnO4-}$ and reducing ion $\ce{C2O4^2-}$ are anions and therefore electrostatically repulsing each other, what makes their reaction slow.
$\ce{Mn^2+}$ ions serve as catalyst,...

Stability of H3MnO4, H2MnO4, HMnO4
One difference between manganese(V) and phosphorus(V) is the former can undergo disproportionation with higher manganese oxidation states available.
Not only $\ce{Mn^VO4^{3-}}$ but also $\ce{Mn^{VI}O4^...
