WebAcids (using the Arrhenius definition) are chemicals which produce H+ ions, while bases are chemicals which produce OH- ions. So when barium hydroxide (Ba (OH)2) and hydrochloric acid (HCl) enter a water solution they will dissociate, or split up. The barium hydroxide will split into one barium ion, Ba^ (2+), and two hydroxide ions, OH-. WebCarbonate ions, CO32- are detected using a dilute acid.

WebJun 15, 2008 · Answer Limestone is mostly made up of the mineral calcium carbonate (CaCO3). This is not very soluble, so rocks don't dissolve very quickly. But if you add an acid, you add hydrogen ions (H+), which will react with the carbonate to form hydrogen carbonate HCO3- ions, which are very soluble in water, and the limestone will dissolve. WebCarbonate ions can be detected by treatment with dilute hydrochloric acid, which produces carbon dioxide gas; this gas can be passed through limewater, turning it cloudy.
