Key Concepts

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

Brønsted-Lowry Acids and Bases

The Brønsted-Lowry theory defines acids as proton donors and bases as proton acceptors. In aqueous solutions, this theory helps predict how substances will behave based on their ability to donate or accept hydrogen ions (H+). Understanding this concept is crucial for determining the acidic or basic nature of a compound, such as Prozac, in solution.

Protonation and Deprotonation

Protonation refers to the addition of a proton (H+) to a molecule, while deprotonation is the removal of a proton. These processes are fundamental in determining whether a substance acts as an acid or a base. For example, if Prozac can donate a proton from its hydroxyl (-OH) group, it may act as an acid; conversely, if it can accept a proton, it may act as a base.

Aqueous Solution Behavior

The behavior of molecules in aqueous solutions is influenced by their interactions with water and the solvent's properties. Water, being a polar solvent, can stabilize ions and facilitate proton transfer. Analyzing how Prozac interacts with water can provide insights into its acidic or basic behavior, as well as its solubility and reactivity in biological systems.
