arehenius theory could not explain the acidic nature of
Answers
Answer:
It fails to explain the acidic nature of substances like CO2, SO2,SO3 etc which do not have hydrogen and similarly it also fails to explain the basic nature of substances like NH3, CaO, MgO etc which do not have -OH group.
It fails to explain the acidic and basic behaviour of substances in solvents other than water such as ammonia,alcohol.etc
The theory fails to explain why strong electrolytes like nitric acid (HNO3) are completely ionized in aqueous solution whereas weak electrolytes like acetic acid (CH3COOH) are ionized to a small extent only.
Explanation:
An Arrhenius acid is a substance that dissociates in water to form hydrogen ions or protons. In other words, it increases the number of H+ ions in the water. In contrast, an Arrhenius base dissociates in water to form hydroxide ions, OH-
