Question

On the surface of polar stratospheric clouds, hydrolysis of chlorine nitrate gives A and B while its reaction with HCl produces B and C. A, B and C are, respectively

• A. $HOCl, HNO_3, Cl_2$
• B. $Cl_2, HNO_3, HOCl$
• C. $HClO_2, HNO_2, HOCl$
• D. $HOCl, HNO_2, Cl_2O$

Answer 1

Answer: (A)

$HOCl, HNO_3, Cl_2$

Answer 2

On the surface of polar stratospheric clouds, hydrolysis of chlorine nitrate as

$ClNO_2+H_2O⟶HOCl(A)+HNO_3(B)$

$ClNO_2+HCl⟶Cl_2(C)+HNO_3(B)$

Hence $A, B$ and $C$ are $HOCl, HNO_3$ and $Cl_2$, respectively.
