Ok let's think! We could use the Bronsted Lowry and Arrhenius theory? What do you think?
Bronsted theory is stating that any compound that can transfer a proton to any other compound is an acid, and the compound that accepts the proton is a base A proton is a nuclear particle with a unit positive electrical charge; it is represented by the symbol H+ because it constitutes the nucleus of a hydrogen atom.
ohhh but what about the Arrhenius one?
Acid- base reactions are characterized by Arrhenius acids, which dissociate in aqueous solution form hydrogen or the later termed hydronium ions and Arrhenius bases which form hydroxide ions.
So arrehnius base would be something like soap or even water because the compunds give OH- in aqueous solutions. Arrhenius acid would be something like hydrochloric acid or even sulfuric acid.
What are they even used for?
Bronsted base would be Ammonia acts as a base when reacting with water to form a hydroxide ion and an ammonium ion and another would be water itself can act as a base when reacting with another water molecule to form a hydroxide ion and a hydronium ion. Bronsted acid would be Hydrochloric acid because it donates a hydrogen ion and acetic acid because it is the proton donor.
