Which compounds are classified as Arrhenius acids?
(1) HCl and NaOH
(2) HNO3 and NaCl
(3) NH3 and H2CO3
(4) HBr and H2SO4



Answer :

pyromorphite
(4) HBr i H2SO4...........

Answer:The correct answer is option 4.

Explanation:

Arrhenius acids are those compounds which gives [tex]H^+[/tex] ions when dissolved in their aqueous solution.

[tex]HA(aq)\rightarrow H^++A^-[/tex]

Arrhenius bases are those compounds which gives [tex]OH^-[/tex] ions when dissolved in their aqueous solution.

[tex]BOH(aq)\rightarrow OH^-+B^+[/tex]

[tex]HBr \& H_2SO_4[/tex] are Arrhenius acids because they form [tex]H^+[/tex]ions in their respective aqueous solution.

[tex]HBr(aq)\rightarrow H^++Br^-[/tex]

[tex]H_2SO_4(aq)\rightarrow 2H^++SO_{4}^{2-}[/tex]

Hence, the correct answer is option 4.
