Any of a class of water-soluble compounds, having sour taste, that turn blue litmus red, and react with some metals to liberate hydrogen, and with bases to form salts. Any compound that easily donates protons; a Brønsted acid lysergic acid diethylamide (LSD) ...
Acid-base catalysis refers to a type of catalysis where the reaction rate is strongly influenced by pH levels and involves the use of Bronsted acids and bases such as H+, OH-, A-, or AH+. By modulating the populations of these reagents through pH control, the reaction rate can be deter...

Acid, any substance that in water solution tastes sour, changes the color of certain indicators (e.g., reddens blue litmus paper), reacts with some metals (e.g., iron) to liberate hydrogen, reacts with bases to form salts, and promotes certain chemical r
