WebThe pH scale is often said to range from 0 to 14, and most solutions do fall within this range, although it’s possible to get a pH below 0 or above 14. Anything below 7.0 is acidic, and anything above 7.0 is alkaline, or basic.

WebJul 20, 2024 · pH = p K a + log [ In −] [ HIn ] Thus at the point where half the indicator is conjugate acid and half conjugate base, pH = p K a +log1 = p K a For phenolphthalein, we have pH = p K a = − log (3 × 10 − 10) = 9.5 so we expect phenolphthalein to change color in the vicinity of pH = 9.5.
