Question

Which substance is always a product when an Arrhenius acid in an aqueous solution reacts with an Arrhenius base in an aqueous solution?

(1) HBr (3) KBr
(2) H2O (4) KOH

Answer 1

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 2

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.
