Which of the following statement are correct when a mixture of `Nacl`

1.	Which of the following statement are correct when a mixture of `Nacl` and `K_(2)Cr_(2)O_(7)` is gently warmed with conc.`H_(2)SO_(4)`?A. Deep red vapours are liberatedB. Deep red vapours dissolved in `NaOH(aq)` forming a yellow solution.C. Greenish yellow gas is liberatedD. Deep red vapour dissolve in water forming yellow solution.
Answer» Correct Answer - ABD `4Cl^(-)+Cr_(2)O_(7)^(2-)+6H^(+) to 2CrO_(2)Cl_(2)uparrow("deep red")+3H_(2)O` `CrO_(2)Cl_(2)+4OH^(-) to CrO_(4)^(2-)("yellow")+2H_(2)O+2Cl^(-)` `CrO_(2)Cl_(2)+H_(2)O to H_(2)CrO_(4)+HCl`
