Identify the acid and base in the given pair. The acid is the species that donates a proton (H⁺), and the base is the species that accepts a proton.
Draw the Lewis structures of the acid and base. This will help visualize the electron flow during the reaction.
Use curved arrows to indicate the movement of electrons. The arrow should start from the electron pair on the base and point towards the hydrogen atom of the acid, showing the base accepting the proton.
Show the formation of the conjugate acid and conjugate base. After the proton transfer, the base becomes the conjugate acid, and the acid becomes the conjugate base.
Verify the stability of the products. Ensure that the conjugate acid and base are more stable than the original acid and base, which is often the case in acid-base reactions.

Key Concepts

Here are the essential concepts you must grasp in order to answer the question correctly.

Acid-Base Theory

Acid-base theory explains the behavior of acids and bases in chemical reactions. According to the Brønsted-Lowry theory, acids are proton donors while bases are proton acceptors. Understanding this concept is crucial for predicting the direction of acid-base reactions and identifying the conjugate acid-base pairs involved.

Reaction Mechanism

A reaction mechanism details the step-by-step process by which reactants transform into products. It includes the breaking and forming of bonds, the movement of electrons, and the intermediates formed during the reaction. Knowing the mechanism helps in understanding how the acid-base pairs interact and the specific pathways taken during the reaction.

Conjugate Acid-Base Pairs

Conjugate acid-base pairs consist of two species that differ by the presence or absence of a proton (H+). When an acid donates a proton, it becomes its conjugate base, and when a base accepts a proton, it becomes its conjugate acid. Recognizing these pairs is essential for analyzing the equilibrium of acid-base reactions and predicting the products formed.
