Answer:
•A Brønsted-Lowry acid is any substance (molecule or ion) that can donate a hydrogen ion ( H+ ).
•A Brønsted-Lowry base is any species that can accept a hydrogen ion ( H+ ).
Explanation:
*example based on the picture*
Take the following reaction for example:
Hydrochloric acid ( HCl ) is the Brønsted-Lowry acid because it donates a hydrogen ion. Ammonia ( NH3 ) is the Brønsted-Lowry base because it accepts the hydrogen ion.
The Brønsted-Lowry theory also introduces the concept of conjugate acid-base pairs. A conjugate acid-base pair are two species that differ by a ( H+ ) ion.
Based on the reaction above, the ammonium ion( NH+4 ) is the conjugate acid of the base ammonia and the chloride ion ( Cl− ) is the conjugate base of hydrochloric acid.
Hope this helps !
