{\A} and {\B} formed in the following reactions are: {\CrO}_2 {\Cl}_2+4 {\NaOH} \to {\A}+2 {\NaCl}+2 {\H}_2 {\O} {\A}+2 {\HCl}+2 {\H}_2 {\O}_2 \to {\B}+3 {\H}_2 {\O} [30-Jan-2024 Shift 2]

Correct Answer is : A=Na2CrO4,B=CrO5

{\A}= {\Na}_2 {\CrO}_4, {\B}= {\CrO}_5

{\A}= {\Na}_2 {\Cr}_2 {\O}_4, {\B}= {\CrO}_4

{\A}= {\Na}_2 {\Cr}_2 {\O}_7, {\B}= {\CrO}_3

{\A}= {\Na}_2 {\Cr}_2 {\O}_7, {\B}= {\CrO}_5
