WebHow much water is required to dilute an acid or a base? Diluting acids and bases To make the pH change by 1, a tenfold dilution is required (eg adding 9 cm 3 of water to 1 cm 3 acid). The acid is becoming less acidic. Similarly, when an alkali is diluted with water the concentration of OH -ions decreases. WebMay 5, 2014 · Dilution reduces the pH of a basic solution. Explanation: The pH of a basic solution is greater than 7. As you dilute a solution, it becomes more and more like pure water. So the pH moves closer to the pH of pure water, pH 7. The pH decreases on dilution. Example: What is the pH of a 10⁻³ mol/L solution of NaOH?
