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.
Explanation:
According to Arrhenius, acid are the substance that produce hydrogen ions when dissolved in a solution.
For example, [tex]HBr \rightarrow H^{+} + Br^{-}[/tex] shows that HBr is an Arrhenius acid.
Whereas Arrhenius bases are the substances that produce hydroxide ions when dissolved in a solution.
For example, [tex]KOH \rightarrow K^{+} + OH^{-}[/tex] 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.
[tex]HBr + KOH \rightarrow KBr + H_{2}O[/tex]
Thus, we can conclude that out of the given options, KBr is the product.
