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)#
