Question

All arhenius acids are also bronsted acids but all arhenius bases are not bronsted bases? comment.

Answer 1

An acid is a substance which can give H+.
A base is a substance which gives OH-.

An acid is a substance which can donate proton.
Thus according to defination of acids ,bronsted and arhenius acids are all same.

But bronsted base is a substance which can accept proton.
while in case of arrhenius base is asubstance which gives OH- and bronsted base should accept proton. Thus all Arrhenius base may not be Bronsted base.

Answer 2

Hey folk...


First let us start wid definations of each :

According to Arrhenius acids are the substances which dissociate in aqueous solution to form hydrogen ions (H+) and bases, which form hydroxide (OH−) ions.

Acoording to Bronsted an acid is a proton donor, and a base is a proton acceptor.



NOW...

According to both the acids are substance which donates proton , but bases can Arrhenius base is a substance which gives OH- and bronsted base should accept proton.

For example NaOH is base according to Arrehenius bcoz it gives OH- ions when dissociates in water but according to Bronsted it is not a base bcoz it doesn't accept prton , So we can say that all arhenius acids are also bronsted acids but all arhenius bases are not bronsted bases.
