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.

the volume of fluid displaced would equal the volume of the gas. use a gas syringe - this is a laboratory instrument that can be used to withdraw a certain volume of gas from a closed system or to measure the volume of gas from a chemical reaction.

with this one i know the answer in craters one reason i looked it up and i learned about it there is my evidence
