explain arhenius and bronsted lowry cocepts of acid and bases.
Answers
According to the Arrhenius theory, a substance which produces hydrogen ion in water, called acid. A substance which produces hydroxide ion in water, called base. According to Bronsted-Lowry theory, an acid is proton donor and base is proton acceptor.
According to the Bronsted-Lowry theory, acid and base react with each other and by an exchange of proton acid, forms its conjugate base and the base forms its conjugated acid.
The Bronsted-Lowry theory is an extended version of an Arrhenius theory of acid-base.
According to the Arrhenius theory, in aqueous solution, acid increases the concentration of H+ ions and base increases the concentration of OH– ions. The limitations of Arrhenius theory was, it identifies the reaction of an acid and base only in the aqueous medium.
