how Arrhenius concept explain the catalytic properties of acid and bases
Answers
Answer:
The Arrhenius acid-base concept classifies a substance as an acid if it produces hydrogen ions H
+
or hydronium ions in water. A substance is classified as a base if it produces hydroxide ions OH
−
in water.
The Arrhenius concept of acids and bases was able to explain a number of phenomenon like neutralization, salt hydrolysis, strength of acids and bases etc.
Limitations of Arrhenius concept:
(a) For the acidic or basic properties, the presence of water is absolutely necessary.
(b) The concept does not explain acidic and basic character of substances in non-aqueous solvents.
(c) The neutralisation process is limited to those reactions which can occur in aqueous solutions only, although reactions involving salt formation do occur in absence of solvent.
(d) It cannot explain the acidic character of certain salts in aqueous solution.
The Arrhenius acid base concept classified a subtance as an acid if it hydrogen ions H+. The Arrhenius concept of acid and base was able to explain a number of phenomenon like neutralize,salt hydrolysis, strength of acid and base etc.
