Correct Answer – A::B::C::D
Yellow phosphorus reacts with `CuSO_(4)` (aq)
`3P_(4)+12CuSO_(4) +24H_(2)O to 4Cu_(3)P +8H_(3)PO_(3)+12H_(2)SO_(4)`
`P_(4)+10CuSO_(4)+16H_(2)O to 10 Cu +4H_(3)PO_(4) +10H_(2)SO_(4)` Hence `CuSO_(4)` (aq) is used to renger harmless any phosphorus (yellow) which has been allowed to come into contact with the skin.
