Question

Q:What kind of reaction is P4 + 3NaOH + 3H2O → 3NaH2PO2 + PH3 :-
(a) oxidation
(b) reduction
(c)redox
(d)none of above​

Answer 1

Answer:

(c) redox

Step-by-step explanation:

A redox reaction is a chemical reaction in which the oxidation states of the chemicals are changed. One species undergoes oxidation (loses electrons), and a species also undergoes reduction (gains electrons). In this reaction, phosphorus changes oxidation state from 0 (in $P_{4}$) to -3 (in $PH_{3}$), which is reduction, and +1 (in $NaH_{2} PO_{2}$), which is oxidation.
