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 \[\operatorname{K} =1 \times 1{{0}^{-}}^{5}\] \[K=\frac{{{\alpha }^{2}}}{V};\,\,\alpha =\sqrt{KV}\] \[=\,\,\,\sqrt{1\times {{10}^{-5}}\times 10};\,\,\,\alpha =1\times {{10}^{-2}}\]You need to login to perform this action.
