Hey guyzz...wasssup?
Can anyone describe the Arrhenius concept fr me?¿
Thanks in advance....♡

Answer:
Arrhenius theory, theory, introduced in 1887 by the Swedish scientist Svante Arrhenius, that acids are substances that dissociate in water to yield electrically charged atoms or molecules, called ions, one of which is a hydrogen ion (H+), and that bases ionize in water to yield hydroxide ions (OH−).
ITS RIVAL WAS THE LOWRY-BRONSTED THEORY WHICH STATED THAT ACIDS ARE PROTON DONORS AND BASES ARE ELECTRON ACCEPTORS

Answer:
In 1884, the Swedish chemist Svante Arrhenius proposed two specific classifications of compounds, termed acids and bases. When dissolved in an aqueous solution, certain ions were released into the solution. As defined by Arrhenius, acid-base reactions are characterized by acids, which dissociate in aqueous solution to form hydrogen ions (H+) and bases, which form hydroxide (OH−) ions.
Acids are defined as a compound or element that releases hydrogen (H+) ions into the solution (mainly water).
NHO3(aq)+H2O(l)→H3O++NO−3(aq)(1)
In this reaction nitric acid (HNO3) disassociates into hydrogen (H+) and nitrate (NO3-) ions when dissolved in water. Bases are defined as a compound or element that releases hydroxide (OH-) ions into the solution.
In this reaction lithium hydroxide (LiOH) dissociates into lithium (Li+) and hydroxide (OH-) ions when dissolved in water.
