10 The Lewis electrondot diagrams of the HSO3 polyatomic ion

10. The Lewis electron-dot diagrams of the HSO3 polyatomic ion and the HSO4 polyatomic ion are shown above at the left and right respectively. Which of the following statements identifies the stronger acid and correctly identifies a factor that contributes to its being the stronger acid? (A) HSO3 (aq) is the stronger acid because its ions experience weaker ion-dipole forces. (B) HSO; (aq) is the stronger acid because the lone pair of electrons on the sulfur atom stabilizes the conjugate base. (C) HSO4 (aq) is the stronger acid because its ions experience stronger ion-dipole forces. (D) HSO4(aq) is the stronger acid because the additional electronegative oxygen atom on the sulfur atom stabilizes the conjugate base.

Solution

D is the correct option.As strong acid is decided by stability of it\'s conjugate base.which is more in Its conjugate base (SO4)2-.
