Write an equation that represents the action in water of perchloric acid as an Arrhenius acid.

HClO₄  →  H⁺  +  ClO₄⁻

Explanation:

Arrhenius acids produce protons when dissolved in aqueous solutions.

Since acids dissociate, they generate protons and a certain anion.

As they give protons to the medium, they can be considered Arrhenius acids.

The equation for perchloric acid is:

HClO₄  →  H⁺  +  ClO₄⁻

One mol of perchloric can produce 1 mol of protons and 1 mol of chlorate anion.

the answers would be

the first one and the second one
