Webb31 juli 2024 · Think of the pH scale as a ruler that we can use to measure how acidic or base something is. There are 14 different possible point values on the scale, and each one represents a possible level of acidity or baseness. A substance is acidic if it has a pH level of 0 through 7, where 0 is the most acidic. Webb24 dec. 2024 · The pH scale is an inverse logarithm that ranges from 0 to 14: anything below 7.0 (ranging from 0.0 to 6.9) is acidic, and anything above 7.0 (from 7.1 to 14.0) is basic (or alkaline ). Extremes in pH in either direction from 7.0 are usually considered inhospitable to life.
