Difficulty: EasyDefinitions and Theories of Acids and Bases

Fill in the blank to complete the statement regarding the Brønsted-Lowry theory of acids and bases.

Answer:According to the Brønsted-Lowry theory, an acid is defined as a species that acts as a proton 【donor】.

Answer

According to the Brønsted-Lowry theory, an acid is defined as a species that acts as a proton donor.
In the Brønsted-Lowry concept, acids are species capable of donating a hydrogen ion (proton, H+H^+) to another chemical species. Therefore, the term 'donor' correctly completes the definition.

Step-by-Step Solution

1
Recall the fundamental definitions of the Brønsted-Lowry acid-base theory.
The Brønsted-Lowry theory defines an acid as a proton (H+H^+) donor and a base as a proton (H+H^+) acceptor.
Acid-base behavior under this theory is governed by the transfer of protons between chemical species.
