Question

When Svante Arrhenius first proposed his acid base theory, he was a doctoral candidate. His professors thought his ideas were unfounded. Within a decade, the Arrhenius theory of acid base was widely accepted and praised within the scientific world. Arrhenius defined acids as compounds having an ionizable hydrogen and bases as compounds with ionizable hydroxides. Eventually scientists adopted a broader theory which includes more compounds to define acids and bases. The Bronsted-Lowry acid base theory defines an acid as a _______ and a base as a ______________.

Answer 1

Answer:

proton donar

proton acceptor

Explanation:

From the given information of the question, Arrhenius acid and base concept is explained, from which a better term to define an acid and base is defined, known as The Bronsted-Lowry acid base theory.

According to The Bronsted-Lowry acid base theory -

An acid is the species which can readily donate a proton, where as, a base is the species, which can readily accept a proton.

Hence, the correct answer is as follow -

proton donar

proton acceptor
