    How many grams of caustic potash required to completely neutralise 12.6 gm \[HN{{O}_{3}}\]

    A) 22.4 KOH

    B) 1.01 KOH

    C) 6.02 KOH

    D) 11.2 KOH

    Correct Answer: D

    Solution :

    \[HN{{O}_{3}}+KOH\to KN{{O}_{3}}+{{H}_{2}}O\]
                \[\frac{12.6}{63}=\]0.2 mole; \[HN{{O}_{3}}\equiv KOH\]
                0.2 mole \[\equiv \] 0.2 mole
                            \[0.2\times 56=11.2gm\].
