A and B formed in the following reactions are:
\(\begin{array}{l} \mathrm{CrO}_{2} \mathrm{Cl}_{2}+4 \mathrm{NaOH} \rightarrow \mathrm{~A}+2 \mathrm{NaCl}+2 \mathrm{H}_{2} \mathrm{O} \\ \mathrm{~A}+2 \mathrm{HCl}+2 \mathrm{H}_{2} \mathrm{O}_{2} \rightarrow \mathrm{~B}+3 \mathrm{H}_{2} \mathrm{O} \end{array}\)
(Jee Main 2024)
\(\begin{array}{l} \mathrm{CrO}_{2} \mathrm{Cl}_{2}+4 \mathrm{NaOH} \rightarrow \mathrm{~A}+2 \mathrm{NaCl}+2 \mathrm{H}_{2} \mathrm{O} \\ \mathrm{~A}+2 \mathrm{HCl}+2 \mathrm{H}_{2} \mathrm{O}_{2} \rightarrow \mathrm{~B}+3 \mathrm{H}_{2} \mathrm{O} \end{array}\)
(Jee Main 2024)
- A = Na2CrO4, B = CrO5
- A = Na2Cr2O4, B = CrO4
- \(\mathrm{A}=\mathrm{Na}_{2} \mathrm{Cr}_{2} \mathrm{O}_{7}, \mathrm{~B}=\mathrm{CrO}_{3}\)
- \(\mathrm{A}=\mathrm{Na}_{2} \mathrm{Cr}_{2} \mathrm{O}_{7}, \mathrm{~B}=\mathrm{CrO}_{5}\)
Answer
(A) A = Na 2 CrO 4 , B = CrO 5
