Chemistry - Redox Reactions Question with Solution | TestHub

A solution is made by mixing 100 ml of 0.2 M - $\mathrm{FeS}{\mathrm{O}}_4$, 100 ml of 0.1 M - $\mathrm{KMn}{\mathrm{O}}_4$ and 300 ml of 1 M - $\mathrm{HCl}{\mathrm{O}}_4$. A reaction occurs in which $\mathrm{F}{\mathrm{e}}^{2+}$ and $\mathrm{Mn}{\mathrm{O}}_4^{-}$ convert to $\mathrm{F}{\mathrm{e}}^{3+}$ and $\mathrm{M}{\mathrm{n}}^{2+}$. If the molarity of ${\mathrm{H}}^{+}$ ion in the final solution is 'x' M, then the value of 1000x is
