Leveling effect

Similarly the strength of a strong base is leveled by the acidity of the solvent.

When a strong acid is dissolved in water, it reacts with it to form hydronium ion (H3O+).

The pH range allowed by a particular solvent is called the acid-base discrimination window.

[citation needed] In a differentiating solvent on the other hand, various acids dissociate to different degrees and thus have different strengths.

For example, anhydrous acetic acid (CH3COOH) as solvent is a weaker proton acceptor than water.
