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

Options

A. hypochlorus and chloric acids
B. hypochlorus and chlorus acids
C. chloric and perchloric acids
D. chloric and hypochlorus acid

Answer

A

Explanation

`{:(Cl_(2)+2NaOH overset("Cold")rarr NaCl + underset("Sod. hypochlorite (P)")(NaClO)),(3Cl_(2)+6NaOh overset("Hot")rarr 5 NaCl + underset("Sod. chlorate (Q)")(NaClO_(3))+3H(2)O):}`
Thus, NaClO (P) and `NaClO_(3)` (Q) are the sodium salts of hypochlorus and chloric acid respectively and hence option (a) is coreect.
