The reactions of `CI_(2)` gas with cold-dilute and hot-concentrated NaOH in water give sodium salts of two different oxioacids of chlorine, P and Q, respectively. The `CI_(2)` gas reacts with `SO_(2)` gas, in presence of charocal, to give a product R reacts with white phosphorus to give a compound S. On hydrolysis, S gives an oxoacid of phosphorus.
P and Q, respectively, are the sodium salts of
A. Hypochlorous and chloric acids
B. Hypochlorous and chlorous acids
C. Chloric and perchloric acids
D. Chloric and hypochlorus acids.
