Why do people/chemists need 3 versions of acids and bases? The Lewis, Bronsted-Lowry, and Arrhenius? I know they have different definitions, but in the end we all use the word acids and bases interchangeably without any note of which type it is? And if we all consider the Lewis version of acids and bases the traditional, why even regard the Arrhenius and Bronsted-Lowry?
These definitions are developed over a period of time.
Like Arrhenius acid -base can be used only when substance give H3+O or OH - in water.
Bronsted -Lowery based definition is more broader explain the acid base reactions in water.
Lewis acid-base is ultimate definition and is not limited in water only or with H+ or OH-.
Like BF3 is a Lewis acid which can be explained by using other definitions.
Ok, thank you!
