For the reaction,

\[ \mathrm{HX(aq)} + \mathrm{H_2O(l)} \xleftrightarrow{\text{gives}} \mathrm{H_3O^+} + \mathrm{X^-} \]

the highest value of $[\mathrm{X^-}]$, when $\mathrm{X^-}$ is

(a)$\mathrm{OCl}^{-}$

(b)$\mathrm{F}^{-\mathrm{w}}$

(c)$\mathrm{Cl}^{-}$

(d)$\mathrm{NO}_{2}{ }^{-}$

Answer

Answer (as printed): C

Explanation

Due to more acidity of $\mathrm{HCl}$ it will undergo more ionization. Hence, concentration of $\mathrm{Cl^{-}}$ will be maximum.
