Reaction Type and Products
The reaction of white phosphorous with aqueous NaOH is a disproportionation reaction that produces phosphine (PH3) and sodium hypophosphite (NaH2PO2).

Oxidation States of Phosphorus
In phosphine, the oxidation state of phosphorus is -3, while in sodium hypophosphite, the oxidation state of phosphorus is +3.

Explanation
Disproportionation reactions occur when a single compound is simultaneously oxidized and reduced to form two different products. In this reaction, white phosphorous (P4) is oxidized to form sodium hypophosphite, where phosphorus has an oxidation state of +3. At the same time, white phosphorous is reduced to form phosphine, where phosphorus has an oxidation state of -3.

Overall, the reaction is a redox reaction because oxidation and reduction occur simultaneously. However, it is classified as a disproportionation reaction because the oxidation and reduction occur within the same compound, leading to the formation of two different products.
