* pH and Concentration: pH is a measure of the concentration of hydrogen ions (H+) in a solution. A lower pH indicates a higher concentration of H+ ions, making the solution more acidic.
* Dilution: Diluting a solution with water reduces the concentration of all dissolved substances, including H+ ions.
* pH Change: As the concentration of H+ ions decreases, the pH value will increase, moving the solution towards a more neutral (pH 7) or even slightly basic range.
Important Note: The exact change in pH depends on the dilution factor (how much water you add). A significant dilution will result in a larger pH increase.
