The answer is (2). The question only ask the production of acid reacts with base. The acid has H+ ion and base has OH- ion. When they react, the production will always contain H2O.

Answer: Option (B) is the correct answer.

Step-by-step explanation:

According to Arrhenius, acid are the substance that produce hydrogen ions when dissolved in a solution.

For example,
HBr \rightarrow H^(+) + Br^(-) shows that HBr is an Arrhenius acid.

Whereas Arrhenius bases are the substances that produce hydroxide ions when dissolved in a solution.

For example,
KOH \rightarrow K^(+) + OH^(-) shows that KOH is an Arrhenius base.

Therefore, when an Arrhenius acid in an aqueous solution reacts with an Arrhenius base in an aqueous solution then following reaction occurs.


HBr + KOH \rightarrow KBr + H_(2)O

Thus, we can conclude that out of the given options, KBr is the product.
