    Degree of dissociation of \[0.1\,\,N\,\,C{{H}_{3}}OOH\] is  \[\left( Dissociation constant = 1\,\,\times \,\,1{{0}^{-}}^{5} \right)\]

    A) \[{{10}^{-5}}\]                       

    B) \[{{10}^{-4}}\]

    C) \[{{10}^{-3}}\]                       

    D) \[{{10}^{-2}}\]

    Correct Answer: D

    Solution :

     Degree of dissociation \[a=?\] Normality of solution \[= 0.1 N \,=\,\,\frac{1}{10}\,N\] \[Volume\text{ }=10\text{ }litre\] Dissociation constant \[\operatorname{K} =1 \times  1{{0}^{-}}^{5}\] \[K=\frac{{{\alpha }^{2}}}{V};\,\,\alpha =\sqrt{KV}\] \[=\,\,\,\sqrt{1\times {{10}^{-5}}\times 10};\,\,\,\alpha =1\times {{10}^{-2}}\]
