Strong oxidising agents such as$\text{P}\text{b}{\text{O}}_2$or sodium bismuthate$\left(\text{N}\text{a}\text{B}\text{i}{\text{O}}_3\right)$oxidise$\text{M}{\text{n}}^{2+}$to$\text{M}\text{n}{\text{O}}_4^{-}$or$\text{M}{\text{n}}^{7+}$.

$2{\text{Mn}}^{2+}+5{\text{PbO}}_2+4{\text{H}}^{+}\to 2{\text{MnO}}_4^{-}+5{\text{Pb}}^{2+}+2{\text{H}}_2\text{O}$
