Question

What defines an amphiprotic species?

a) Capable of acting as both an acid and a base
b) Capable of conducting electricity
c) Always found in aquatic environments
d) Inert to chemical reactions

Answer 1

An amphiprotic species is a substance that can act as both an acid and a base in a chemical reaction. Water is an example of an amphiprotic species.

Step-by-step explanation:

An amphiprotic species refers to a substance that can act as both an acid and a base in a chemical reaction. These species can either gain or lose a proton and exhibit amphoterism.

For example, water (H2O) is an amphiprotic species. It can act as an acid by donating a proton (as in its reaction with ammonia) or as a base by accepting a proton (as in its reaction with hydrogen fluoride).

Other examples of amphiprotic species include the bicarbonate ion (HCO3-) and amino acids.
