    The reaction of white phosphorous with aqueous NaOH gives phosphine along with another phosphorous containing compound. The reason type , the oxidation state of phosphorous in phosphine and in the other products are, respectively,

    Oxidation states of phosphorous in phosphinic acid, phosphonic acid and metaphosphoric acid

    Phosphorous forms two types of oxyacids, one having phosphorous in +1 or +3 oxidation state and other having phosporous in +1 or +3 oxidation state and other having phosphorous in +4 or +5 oxidation state. Phosphorous acids act as reducing agents as they tend to disproportionate. The important oxyacids of phosphorous are: H_(3)PO_(2),H_(3)PO_(3),H_(3)PO_(4),HPO_(3),H_(4)P_(2)O_(6),H_(4)P_(2)O_(7) . The number of OH group or groupds in oxoacids of phosphorous decides the basicity of the acid. Basicity of H_(3)PO_(2) is:
