Answer : The Bronsted-Lowry theory was not against the Arrhenius theory, rather it was just a modification to the previous theory of acids and bases. Hydroxide ions are considered as bases because they have the tendency to accept hydrogen ions from acids and form water.
An acid was the one which produces hydrogen ions in solution because it reacts with the water molecules by giving a proton to them.
In a nutshell, he described bases as hydrogen acceptor and acids as hydrogen donors.
