Question

Which chemical equation represents the reaction of an Arrhenius acid and an Arrhenius base?

Answer 1

The chemical equation that represents the reaction of an Arrhenius acid and an Arrhenius base is 1) HC2H3O2 (aq) + NaOH (aq) ---> NaC2H3O2 (aq) + H2O (I) 

Answer 2

Answer : The correct option is, (1)

Explanation :

According to the Arrhenius acid-base concept,

Arrhenius acid is a species that produces $H^+$ ion in an aqueous solution and Arrhenius base is a species that produces $OH^-$ ion in an aqueous solution.

From the given options, option 1 chemical equation represents the reaction of an Arrhenius acid and an Arrhenius base. In this reaction, $HC_2H_3O_2$ produces $H^+$ ion in an aqueous solution and act as an Arrhenius acid, $NaOH$ produces $OH^-$ ion in an aqueous solution and act as an Arrhenius base.

While the other options does not represents the reaction of an Arrhenius acid and an Arrhenius base.

Reaction 2 is an example of combustion reaction.

Reaction 3 is an example of single-displacement reaction.

Reaction 4 is an example of double-displacement reaction.

Hence, the correct option is, (1)
