    The product(s) formed when \[{{H}_{2}}{{O}_{2}}\] reacts with disodium hydrogen phosphate is

    A)  \[{{P}_{2}}{{O}_{5}}\,\,.\,N{{a}_{3}}P{{O}_{4}}\]

    B)  \[N{{a}_{2}}HP{{O}_{5}}\,\,.\,{{H}_{2}}{{O}_{2}}\]

    C)  \[Na{{H}_{2}}P{{O}_{4}},\,\,\,{{H}_{2}}O\]

    D)  \[N{{a}_{2}}HP{{O}_{4}}\,\,.\,{{H}_{2}}O\]

    Correct Answer: B

    Solution :

    \[{{H}_{2}}{{O}_{2}}\] form addition product with disodium hydrogen phosphate. \[{{H}_{2}}{{O}_{2}}+N{{a}_{2}}HP{{O}_{2}}\xrightarrow{{}}\underset{addition\text{ }product}{\mathop{N{{a}_{2}}HP{{O}_{4}}\,.\,\,{{H}_{2}}{{O}_{2}}}}\,\]
