What is the definition of a base?

A. Bases accept protons.
B. Bases are proton donors.
C. Bases increase the number of protons in an aqueous solution.
D. Bases donate protons to water molecules.



Answer :

Final answer:

Bases accept hydrogen ions from solutions according to the Bronsted-Lowry theory in chemistry.


Explanation:

Bases can be defined as hydrogen ion acceptors, accepting hydrogen ions from hydronium ions in solutions. According to the Bronsted-Lowry theory, acids donate protons while bases accept protons. For example, when the base ammonia (NH3) dissolves in water, it accepts hydrogen ions to form ammonium ions (NH4+) and hydroxide ions (OH-).
