Which substance is an Arrhenius acid?
(1) LiF(aq) (3) Mg(OH)2(aq)
(2) HBr(aq) (4) CH3CHO


Sagot :

HBr (aq) is an Arrhenius acid.
The equation is HBr(aq) -> H+ + Br- 

Answer: Option (2) is the correct answer.

Explanation:

Arrhenius acid are the species that donate a [tex]H^{+}[/tex] ion or proton.

For example, [tex]HBr \rightarrow H^{+} + Br^{-}[/tex]

Whereas LiF, [tex]Mg(OH)_{2}[/tex], and [tex]CH_{3}CHO[/tex] are the substances which do not give a proton upon dissociation. Hence, they are not Arrhenius acids.

Therefore, we can conclude that [tex]HBr(aq)[/tex] substance is an Arrhenius acid.
