Question

Need a light? I am a transparent waxy-like solid element which emits light continuously

Answer 1

Translucent waxy solid is actually white phosphorus (P4)

P4 on heating gives red phosphorus in an inert atmosphere

P4 on reaction with KOH gives phosphine, a poisonous gas

P4+KOH+H2O⇒PH3+KH2PO2

now P4 on excess of chlorine gives PCl5 which on hydrolysis gives POCl3 and H3PO4

P4+10Cl2⇒4PCl5

PCl5+H2O⇒POCl3+2HCl

POCl3+3H2O⇒H3PO4+3HCl

A:P4(white),B:P4(red),C:PH3,D:PCl5,E:H3PO4

How satisfied are you with the answer?
