(a)

Interpretation Introduction

Interpretation:

The compound $\left({\text{H}}_{\text{2}}{\text{SO}}_{\text{4}}\left(\text{or}\right){\text{NH}}_{\text{4}}{}^{\text{+}}\right)$ that forms stronger conjugate base has to be given.

Concept Introduction:

Bronsted-Lowry Acids:  A Bronsted-Lowry acid is proton donor and contains a hydrogen atom.  It may be a neutral molecule or may contain a net positive or negative charge.

Conjugate base:  A conjugate base is the product formed by a loss of proton from an acid.  The conjugate base of the acid A will be ${\text{A}}^{\text{-}}\text{.}$

(b)

Interpretation Introduction

Interpretation:

The compound $\left(\text{HF}\left(\text{or}\right){\text{H}}_{\text{2}}\text{O}\right)$ that forms stronger conjugate base has to be given.
