Question

The conjugate acid of $H{S}^{-}$ is

• A. $S^{2-}$
• B. $H_{2}S$
• C. Both (a) and (b)
• D. None of these

Answer 1

Answer: (B)

$\underset{\text{conjugate add }}{H_{2}S}\stackrel{+\mathrm{H}{}^{+}}{\rightleftharpoons }\underset{\text{amphoteric }}{H{S}^{-}}\stackrel{-\mathrm{H}{}^{+}}{\rightleftharpoons }\underset{\text{conjugate base}}{S^{2-}}$
