Answer: Option (A) is the correct answer.
Explanation:
Arrhenius acids are the species which dissociate to give hydrogen ions, that is, [tex]H^{+}[/tex].
For example, [tex]CH_{3}COOH + H_{2}O \rightleftharpoons H_{3}O^{+} + CH_{3}COO^{-}[/tex]
In the given example, HCN is donating the hydrogen ion therefore, it is an acid whereas [tex]HPO^{2-}_{4}[/tex] is accepting the hydrogen ions so it acts as a base.
Whereas according to Arrhenius, bases are the species which dissociate to give hydroxide ions, that is, [tex]OH^{-}[/tex].
For example, [tex]NaOH + H_{2}O \rightarrow Na^{+} + OH^{-}[/tex]
Thus, we can conclude that the statement only positive ion in solution is [tex]H^{+}[/tex] best describes the solution produced when an Arrhenius acid is dissolved in water.
A) The only positive ion in the solution is H.
Arrhenius concept:
Arrhenius acids are the species that dissociate to give hydrogen ions, that is, H+ .
Dissociation of acetic acid is as follows:
[tex]CH_3COOH+H_2O < = > H_3O^++CH_3COO^-[/tex]
In the given example, CH₃COOH is donating the hydrogen ion therefore, it is an acid whereas water acts as a base as it is accepting Hydrogen ion.
Thus, we can conclude that the statement only positive ion in solution best describes the solution produced when an Arrhenius acid is dissolved in water.
