Step 1

The acid is the one that donates the proton and the base is the one that accepts it. In this case, $H_{2}SO_{4}$ is the acid because it donates a proton to become $HSO_{4}^{-}$, and $SO_{3}^{2-}$ is the base because it accepts a proton to become $HSO_{3}^{-}$. Show more…

Key Concepts

Conjugate Acid-Base Pair

A conjugate acid-base pair consists of two species that differ by a single proton. When an acid donates a proton, it forms its conjugate base, and when a base accepts a proton, it forms its conjugate acid. This concept is essential for analyzing acid–base reactions because identifying these pairs helps in understanding the changes that occur during the proton transfer process.

Bronsted-Lowry Acid-Base Theory

This theory defines an acid as a species that donates a proton (H?) and a base as a species that accepts a proton. It forms the foundation for understanding acid–base reactions by focusing on the proton transfer that occurs between reactants, allowing us to identify which components of a reaction are acting as acids and which as bases.
