White phosphorus reacts with calcium to give a certain compound. This compound on hydrolysis produces:
The reactions of Cl2 gas with cold-dilute and hot-concentrated NaOH in water give sodium salts of two different oxoacids of chlorine, P and Q, respectively. The Cl2 gas reacts with SO2 gas, in presence of charcoal, to give a product R reacts with white phosphorus to give a compound S. On hydrolysis, S gives an oxoacid of phosphorus. 3. P and Q, respectively, are the sodium salts of
Which of the following produces PCl3 ?
