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.

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.
