• An oxygen-containing acid.
  • This term was formerly used to distinguish an acid containing oxygen from one in which this element is not present, as sulphuric acid, H<sub>2</sub>SO<sub>4</sub>, from hydrochloric; acid, HCl. In modern organic chemistry the same term is often applied to an acid which contains both a carboxyl and a hydroxyl group, as oxyacetic or glycolic acid, CH<sub>2</sub>.HO.COOH. Substances of this kind are perhaps better called <internalXref urlencoded="hydroxyacids">hydroxyacids</internalXref> or <em>alcohol acids.</em>
  • An acid containing oxygen. Also called <internalXref urlencoded="oxacid">oxacid</internalXref>.
  • An acid containing oxygen, as chloric acid or sulphuric acid; -- contrasted with the <contr>hydracids</contr>, which contain no oxygen, as hydrochloric acid. See <xref urlencoded="acid">acid</xref>, and <xref urlencoded="hydroxy-">hydroxy-</xref>.
  • An <xref>acid</xref> containing <xref>oxygen</xref>, as opposed to a <xref>hydracid</xref>.
