compounds that give hydroxide ion OH^(-) in aqueous solution.

Explanation:

Arrhenius definition of bases: compounds that give hydroxide ion OH^(-) in aqueous solution.

Example: NaOH, Ca(OH)_2, H_2O, etc...

This is a limited definition of bases, therefore, Brønsted-Lowry definition is broader: Bases are compounds that accept hydrogen ion H^+.

Example: NH_3.

NH_3(aq)+H^(+)(aq)->NH_4^(+)(aq)
