Final answer:
A Brønsted-Lowry base is any species that can accept a proton (or hydrogen ion) from another molecule. Examples of Brønsted-Lowry bases include hydroxide ions (OH¯), water (H₂O), and ammonia (NH₃).
Step-by-step explanation:
A Brønsted-Lowry base is any species that can accept a proton (or hydrogen ion) from another molecule. Examples of Brønsted-Lowry bases include hydroxide ions (OH¯), water (H₂O), and ammonia (NH₃). These substances have the ability to accept a proton and therefore act as bases according to the Brønsted-Lowry definition.
