The species which will behave both as a conjugate acid and base is :(a) NH4OH (b) \(CO^-_3\)(c) \(HSO^-_4\)(d) H2SO4

Answer»

(C) \(HSO_4^-\)

\(HSO_4^-\) can behave both as a conjugate acid and base.

\(\underset{\text{acid}}{HSO^-_4}\longrightarrow H^+\underset{\text{conjugate base}}{SO^-_4}\)

\(\underset{\text{base}}{HSO^-_4}\longrightarrow H^+\underset{\text{conjugate acid}}{H_2SO_4}\)

Option : (c) \(HSO^-_4\)
