Which compounds are classified as Arrhenius acids?

Olenka [21]

Answer:The correct answer is option 4.

Explanation:

Arrhenius acids are those compounds which gives $H^+$ ions when dissolved in their aqueous solution.

$HA(aq)\rightarrow H^++A^-$

Arrhenius bases are those compounds which gives $OH^-$ ions when dissolved in their aqueous solution.

$BOH(aq)\rightarrow OH^-+B^+$

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

$HBr(aq)\rightarrow H^++Br^-$

$H_2SO_4(aq)\rightarrow 2H^++SO_{4}^{2-}$

Hence, the correct answer is option 4.
