Question

5. Which type of substance yields hydrogen ions, H+, in

an aqueous solution?
A) an Arrhenius acid
B) an Arrhenius base
C) a saturated hydrocarbon
D) an unsaturated hydrocarbon

Answer 1

Answer: An Arrhenius acid is a type of substance yields hydrogen ions,
`H^(+)`, in an aqueous solution.

Step-by-step explanation:

Substances that give dissociate to give hydrogen ions or protons when dissolved in an aqueous solution are called Arrhenius acid.

For example, HCl is a strong acid and upon dissociation in water it gives the following ions.

`HCl \rightarrow H^(+) + Cl^(-)`

Thus, we can conclude that an Arrhenius acid is a type of substance yields hydrogen ions,
`H^(+)`, in an aqueous solution.
