Answer: d. An acid
Explanation:
According to Arrhenius concept, a base is defined as a substance which donates hydroxide ions [tex](OH^-)[/tex] when dissolved in water and an acid is defined as a substance which donates hydrogen ions [tex](H^+)[/tex] in water.
A substance that increases the hydrogen ion concentration of a solution is an Arrhenius acid.
[tex]HNO_3\rightarrow NO_3^-+H^+[/tex]
Thus as [tex]HNO_3[/tex] donates a proton , it is considered as an Arrhenius acid.
Answer:
Option D is correct. According to the Arrhenius concept, if [tex]\rm \bold {HNO_3}[/tex] were dissolved in water, it would act as an Acid.
Explanation:
According to Arrhenius,
An acid is a hydrogen-containing compound that release [tex]\rm \bold {H^+}[/tex] in water after dissociation.
A base is a hydroxide-containing compound that release [tex]\rm \bold OH^-[/tex] in water after dissociation.
The reaction of dissociation of [tex]\rm \bold {HNO_3}[/tex] in water is,
[tex]\rm \bold {HNO_3\rightarrow H^++NO_3^-}[/tex]
In the reaction [tex]\rm \bold {HNO_3}[/tex] when dissolved in water dissociates to release [tex]\rm \bold {H^+}[/tex], hence it is an acid.
[tex]\rm \bold {HNO_3}[/tex] does not release any [tex]\rm \bold OH^-[/tex]. Hence Option B and C can be eliminated.
It releases proton, not accept. Hence option A is also incorrect.
On the basis of the above discussion we can say that according to the Arrhenius concept if [tex]\rm \bold {HNO_3}[/tex] were dissolved in water, it would act as an Acid.
