I know the definition of and Arrhenius/brosted acid/base, but I dont really undersrand the difference between them.

For example, lets look at NH3. I know its a Bronsted base. BUt is it an Arrhenius base? If you put NH3 in water it, wouldnt it increase the concentration of OH by taking away hydrogens from H20? I read somewhere an Arrhenius base HAS to contain an OH, like NaOH, but I'm not sure if thats true..

Maybe NH3 is only an Arrhenius base if it's reacting with water, but not if its reacting with something else? Idk, any insight would help
