Acids and bases
... Non-aqueous solvents that are good proton acceptors (e.g.NH3) encourage acids to ionize in them. In a basic solvent, all acids are strong. The solvent is said to exhibit a levelling effect on the acid, since the strength of the dissolved acid cannot exceed that of the protonated solvent. In ...
