WebWhy are buffer solutions used to calibrate pH? Buffer solutions are used to calibrate pH meters because they resist changes in pH. When you use a pH meter to measure pH, you want to be sure that if the meter says pH = 7.00, the pH really is 7.00. So you use solutions of known pH and adjust the meter to display those values. WebThe pH is equal to 9.25 plus .12 which is equal to 9.37. So let's compare that to the pH we got in the previous problem. For the buffer solution just starting out it was 9.33. So we …
