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

Solution

On the surface of polar stratospheric clouds, chlorine nitrate ($$ClONO_2$$) undergoes hydrolysis: $$ClONO_2 + H_2O \rightarrow HOCl + HNO_3$$, so A = HOCl and B = $$HNO_3$$. The reaction with HCl is $$ClONO_2 + HCl \rightarrow Cl_2 + HNO_3$$, producing B = $$HNO_3$$ and C = $$Cl_2$$. Thus A = HOCl, B = $$HNO_3$$, C = $$Cl_2$$, which matches Option A.

The answer is $$\boxed{\text{Option A}}$$.
