    What is the oxidation state of P in Ba\[{{({{H}_{2}}P{{O}_{2}})}_{2}}\]?

    A)  +1                                         

    B)  +2

    C)  +3                                         

    D)  -1

    Correct Answer: A

    Solution :

                     Let oxidation state of P is x, then 2 (+1) + 2[2(+1) + x + 2(-2)] = 0                 2 + 2(2 + x - 4) = 0                                 2 + 4 + 2x - 8 = 0                                                 2 + 2 x - 4 = 0                                                                 2x = 2 \[\therefore \]                                                       x = + 1
