The oxids are grouped as acid-forming, basic, or neutral. The acid-forming oxids, also called acid anhy drids, are compounds of oxygen with negative or acid radicals. Most of them unite directly with water to form acids, as sulphuric oxid, 803, which unites with water to form sulphuric acid, H2SO4. The basic oxids are compounds of oxygen with positive elements. Many of them form hydroxids, all of which neutralize acids, forming salts, as barium oxid, BaO, which forms the hydrate Ba(OH)2. The neutral oxids or peroxids usually contain more oxygen than the others, and have only very feeble acid or basic properties. Certain oxids cannot be cla ed with any of these groups, having both acid and basic properties. oxid ability (ok"si-da-bil'i-ti), n. [
