White phophorus reacts with caustic sod...

White phophorus reacts with caustic soda, the products are `PH_(3)` and `NaH_(2)PO_(2)`. This reaction is an example of `:`

A

oxidation

B

reduction

C

disproportionation

D

neutralisation

Text Solution

Verified by Experts

The correct Answer is:
C
`P+3NaOH+3H_(2)Orarr3NaH_(2)PO_(2)+PH_(3)` O.N of P in `NaH_(2)PO_(3) and PH_(3)` are +1 and -3 respectively. Therefore, in this reaction P undergoes disproportionation.

Redox is a reaction in which both oxidation and reduction will take place simultaneously . It is obvious that if one substance gives electron there must be another substance to accept these electrons . In some reactions, same substance is reduced as well as oxidised, these reactions are termed as disproportionation reactions. For calculating equivalent mass in redox reaction change in oxidtaion number is realted to n-factor which is reciprocal of molar ratio.
