Question

Which statement describes an Arrhenius acid?
It is a proton donor.
It is a proton acceptor.
It produces hydroxide ions in a solution.
It produces hydrogen ions in a solution.

Answer 1

It produces hydrogen ions in a solution.

Answer 2

The correct option is this: IT PRODUCES HYDROGEN IONS IN A SOLUTION.

An Arrhenius acid refers to a substance that dissociate in water to form protons or hydrogen ions; the acid usually increases the number of hydrogen ions in aqueous solution. In aqueous solutions, the hydrogen ions react with water molecules to from hydronium ions, H3O+. In neutralization reaction, an Arrhenius acid and base will react together to form salt and water.
