Statement 1: Permanganate titrations is not carried out in presence of hydrochloric acid.

Statement 2: Hydrochloric acid is oxidised to chlorine.

Permanganate titrations are not carried out in presence of HCI because it may oxidise some of the HCI to ${\mathrm{Cl}}_2$ gas according to the following chemical reaction; $2{\mathrm{MnO}}_4^{-}+16{\mathrm{H}}^{+}+10{\mathrm{Cl}}^{-}\to 2{\mathrm{Mn}}^{2+}+8{\mathrm{H}}_2\mathrm{O}+5{\mathrm{Cl}}_2$. Hence we do not get the correct end point for the given titration.
