(OH-) ions. When a solution has a preponderance of hydroxide ions, its pH is above 7 (the neutral point), and the solution is alkaline. Acids and bases that behave this way are known as Arrhenius acids and bases. Hydrogen chloride (HCl) is an example of an Arrhenius acid, and sodium...

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...
