BasesLewis acids and bases play an important role in chemical reactions because‚ except oxidation-reduction reactions‚ almost every reaction could be categorized as an acid-base reaction. Bases in water solutions show certain specific characteristics: bitter taste‚ feel slippery‚ and turn litmus paper blue.

Two key factors that contribute to the ease of deprotonation are the polarity of the H—A bond and the size of atom A‚ which determines the strength of the H—A bond. Acid strengths are also often discussed in terms of the stability of the conjugate base. Sulfonic acids‚ which are organic oxyacids‚ are a class of strong acids. A common example is toluenesulfonic acid (tosylic acid). Unlike sulfuric acid itself‚ sulfonic acids can be solids. Superacids are acids stronger than 100% sulfuric acid. Examples
