Leveling Effect
What is Leveling Effect?
The leveling effect describes the phenomenon in which a solvent limits (levels) the apparent strength of strong acids or bases dissolved in it. In water, all strong acids are completely dissociated and appear equally strong, because water acts as a sufficiently strong base to accept a proton from any strong acid. The intrinsic differences in strength among strong acids can only be observed in solvents that are weaker bases than water (differentiating solvents), such as glacial acetic acid.
