HI is obtained by the reaction of KI with conc.${\mathrm{H}}_2\mathrm{S}{\mathrm{O}}_4$, is further oxidized by${\mathrm{H}}_2\mathrm{S}{\mathrm{O}}_4$, because HI is strong reducing agent.
$2\mathrm{K}\mathrm{I}+{\mathrm{H}}_2\mathrm{S}{\mathrm{O}}_4\to {\mathrm{K}}_2\mathrm{S}{\mathrm{O}}_4+2\mathrm{H}\mathrm{I}$
$2\mathrm{H}\mathrm{I}+{\mathrm{H}}_2\mathrm{S}{\mathrm{O}}_4\to {\mathrm{I}}_2+\mathrm{S}{\mathrm{O}}_2+2{\mathrm{H}}_2\mathrm{O}$
