Dissolution is the process by which a solute dissolves in a solvent to form a solution and is influenced by a variety of factors. The correct answer highlights the significance of ionic strength, pH, and buffer capacity in this process.

Ionic strength plays a crucial role in influencing the solubility of ions in a solution. It affects the interactions among solute particles and between solute and solvent, thereby altering dissolution rates. Higher ionic strength typically leads to increased interactions between ions in solution, which can modify solubility.

pH is another critical factor in dissolution, especially for substances that can exist in different ionic forms depending on the acidity or basicity of the solution. Changes in pH can protonate or deprotonate solutes, affecting their solubility. For example, an acidic environment might increase the solubility of certain salts that are basic in nature.

Buffer capacity relates to the ability of a solution to maintain a stable pH when acids or bases are added. Buffers help keep the pH within a specific range, which can optimize the conditions for dissolution by preventing drastic changes that might affect solubility.

These factors collectively contribute to the dynamics of how substances dissolve in solvents. Understanding their roles aids
