Answer» A deep red vapours is evolved The vapours when passed into NaOH solution GIVES a YELLOW solution of `Na_2CrO_4` Chlorine gas is evolved Chromyl chloride is formed Solution :`K_2Cr_2O_7 +Cl^(-) rarr underset("(Red)")(CrO_2Cl_2) uarr` `CrO_2Cl_2 + NaOH rarr underset("(Yellow Solution)")(Na_2CrO_4) overset(PB^(+2))rarr underset("(Yellow ppt)")(PbCrO_4uarr)`
