Answer» (D) \(H_2 SO_4 ,HSO_4^-\) An acid and a base which differ only by the presence or absence of a proton are called a conjugate acid-base pair. Here, \(H_2SO_4\), is acid and \(HSO^-_4\) is its conjugate base. Option : (d) H₂SO₄,\(HSO^-_4\)

Which of the following is a conjugate acid-base pair ? (a) HCl, NaOH (b) KCN, HCN (c) NH4Cl, NH4OH (d) H2SO4,\(HSO^-_4\)

Answer»

(D) \(H_2 SO_4 ,HSO_4^-\)

An acid and a base which differ only by the presence or absence of a proton are called a conjugate acid-base pair.

Here, \(H_2SO_4\), is acid and \(HSO^-_4\) is its conjugate base.

Option : (d) H₂SO₄,\(HSO^-_4\)
