How does dilution affect the pH of basic solution?

Dilution affects the pH of a basic solution by decreasing its pH, but it will still remain above 7, indicating that the solution is still basic. Here's a detailed explanation: Concentration of Hydroxide Ions: In a basic solution, the pH is determined by the concentration of hydroxide ions. Effect of Dilution: When a basic solution is diluted, the concentration of hydroxide ions decreases because the same amount of solute (base) is now dispersed in a larger volume of solvent (water). Change in pH: As the concentration of hydroxide ions decreases, the pOH increases. Since pH is inversely related to pOH (pH = 14 - pOH), a higher pOH results in a lower pH. However, because the solution is basic, the pH will remain greater than 7.
