It is based on the proton. A proton acceptor is a base whereas a proton donour is known as an acid.
Adding an acid base indicator to a sodium hydroxide solution can verify that it is an alkaline solution. For example, phenolphthalein turns pink in an NaOH solution.
Since protons are always transferred in the Arrenhius concept, all Arrhenius acid/base reactions are also Bronsted-Lowry acid/base reactions.
accoring to lewis concept it is base H^+(lewis acid) + H^2O(lewis base)---->(H^3O)^+
Gilbert N, Lewis
According to this concept an acid is a compound which donates a proton (H+). for example, HA + H2O ------------> A- + H3O+ acid water base hydronium ion

A neutralization reaction is a reaction between a base and an acid; the products are a salt and water.

acc. to this concept , acids are proton donor and base are proton acceptor . reverse of these reactions are also acid base pairs and the pairs are known as conjugate acid base pairs . .
What is Arrhenius concept of acid and base?The universal aqueous acid-base definition of the Arrhenius concept is described as the formation of water from hydrogen and hydroxide ions, or hydrogen ions and hydroxide ions from the dissociation of an acid and base in aqueous solution:H+ (aq) + OH− (aq) H2O(In modern times, the use of H+ is regarded as a shorthand for H3O+, since it is now known that the bare proton H+ does not exist as a free species in solution.)This leads to the definition that in Arrhenius acid-base reactions, a salt and water is formed from the reaction between an acid and a base. In other words, this is a neutralization reaction.acid+ + base− → salt + water
NaOH is a base.As it gives hydroxyl ion in water acc to arrehenious concept.
It depends which part of the stong acid concept you are concerned with: A weak acid is the opposite of a "strong" acid A strong base is the opposite of a strong "acid" A neutral solution is the oppposte of a strong acid (a reactive solution)
An acid can turn into a base if you mix a much stronger base with it! That way the base acid overpowers the acid and makes the acid a base!
Acid + base conjugate base + conjugate acid
