Q38 / 170 · Manipal (MET) 2017 · Chemistry

The conjugate base of the acid $\mathrm{H}_2 \mathrm{~S}$ is

  • Correct answer
    A
    $\mathrm{HS}^{-}$
  • B
    $\mathrm{S}^{2-}$
  • C
    S
  • D
    None of these

Solution

The conjugate base of the acid $\mathrm{H}_2 \mathrm{~S}$ is $\mathrm{HS}^{-}$. $\underset{\text { Acid }}{\mathrm{H}_2 \mathrm{~S}} \rightleftharpoons \underset{\substack{\text { Conjugate } \\ \text { base }}}{\mathrm{HS}^{-}}+\mathrm{H}^{+}$

Hence, the correct answer is option: 'A'.
