Chemical And Ionic Equilibrium Result Question 33
33. Of the given anions, the strongest base is
(1981,1 M)
(a) $\mathrm{ClO}^{-}$
(b) $\mathrm{ClO}_2^{-}$
(c) $\mathrm{ClO}_3^{-}$
(d) $\mathrm{ClO}_4^{-}$
Show Answer
Answer:
Correct Answer: 33. ( a )
Solution:
- The order of acidic strength of conjugate acids is
$ \mathrm{HOCl} < \mathrm{HClO} _2 < \mathrm{HClO} _3 < \mathrm{HClO} _4 $
Reverse is the order of basic strength of their conjugate base, i.e. $\mathrm{ClO}^-$ is the strongest base.
