Select the reaction which describes the existence of ${\mathrm{I}}_2{\mathrm{O}}_5\left(s\right)$ as $\left({\mathrm{IO}}_2^{+}\right)\left({\mathrm{IO}}_3^{-}\right)$:

The reaction which describes the existence of ${\mathrm{I}}_2{\mathrm{O}}_5\left(s\right)$ as $\left({\mathrm{IO}}_2^{+}\right)\left({\mathrm{IO}}_3^{-}\right)$,

so, that correct option ${\mathrm{I}}_2{\mathrm{O}}_5+\mathrm{HF}⟶{\mathrm{IO}}_2\mathrm{F}+{\mathrm{HIO}}_3$.

Hence, correct option is B.
