Here are the essential concepts you must grasp in order to answer the question correctly.
Solubility and pH
The solubility of certain compounds can be affected by the pH of the solution. In acidic solutions, the concentration of hydrogen ions (H+) increases, which can shift equilibria and enhance the solubility of some salts, particularly those containing basic anions that can react with H+.

Common Ion Effect
The common ion effect describes how the solubility of a salt decreases in a solution that already contains one of its constituent ions. In acidic solutions, the presence of H+ can influence the solubility of salts like AgBr by shifting the dissolution equilibrium, potentially increasing solubility if the anion reacts with H+.

Net Ionic Equations
A net ionic equation represents the actual chemical species that are involved in a reaction, excluding spectator ions. For dissolution reactions, it shows the ions produced when a compound dissolves in solution, allowing for a clearer understanding of the chemical processes occurring, especially in the context of solubility changes.
