Redox Reactions

Question
CBSEENCH11006659
Wired Faculty App

Calculate the oxidation number of P in Ba(H2PO2)2.

Solution
Let x be the oxidation number of P.
Oxidation number of Ba =+2
Oxidation state of O2 =-2
Thus, oxidation number of P in Ba(H2PO2)2         
 
        +2 + 4(1) + 2x + 4(-2) = 0
  or    2x - 2 = 0    or  x = + 1
