Chlorine, upon reaction with iodate ion in a basic medium, produces anion $\mathbf{P}$, which is an anion of the pentabasic oxyacid orthoperiodic acid, ${\mathbf{P}}^{\prime }$ (i.e., ${\mathrm{H}}_5{\mathrm{IO}}_6$), according to the equation:

${\mathrm{IO}}_3^{-}$ + $x{\mathrm{OH}}^{-}$ + ${\mathrm{Cl}}_2$$\to$$\mathbf{P}$ + $y{\mathrm{H}}_2\mathrm{O}$ + $z{\mathrm{Cl}}^{-}$

(where $x$, $y$, and $z$ are the stoichiometric coefficients in the balanced equation).

Compound (${\mathbf{P}}^{\prime }$) on heating undergoes the following changes:

$$2P\underset{Excess}{\overset{H^{+}}{\to }}2P^{\prime }\underset{-4H_{2}O}{\overset{100{℃}^{}}{\to }}2Q\underset{-H_{2}O}{\overset{200{℃}^{}}{\to }}\left(R\right)+S\uparrow$$

$\mathbf{R}$ can be used in the quantitative estimation of $\mathrm{CO}$.

Which of the following statement(s) is/are CORRECT?
