  • Oxyacid

    A covalent compound with hydrogen ions bonded to polyatomic ions containing oxygen.
  • Polyatomic ion

    An ion composed of two or more atoms covalently bonded, acting as a single unit.
  • Nitrite ion

    A polyatomic ion with the formula NO2-.
  • Sulfite ion

    A polyatomic ion with the formula SO3^2-.
  • Nitrous acid

    An oxyacid with the formula HNO2, formed from nitrite ion.
  • Sulfuric acid

    An oxyacid with the formula H2SO3, formed from sulfite ion.
  • Oxyacid strength rule

    A rule stating that an oxyacid is strong if it has two or more oxygens than hydrogens.
  • Electronegativity

    A measure of an atom's ability to attract and hold electrons.
  • Oxalic acid

    An exception to the oxyacid strength rule, with low central element electronegativity.
  • Iodic acid

    An exception to the oxyacid strength rule, with low central element electronegativity.
  • Hypoiodous acid

    An oxyacid with fewer remaining oxygens compared to iodic acid.
  • Central element

    The non-hydrogen element in an oxyacid, affecting its acidity.
  • Group 6a

    A group in the periodic table containing oxygen, sulfur, and selenium.
  • Remaining oxygens

    The number of oxygens left after subtracting hydrogens in an oxyacid.
  • Acidity

    The strength of an acid, influenced by remaining oxygens and central element electronegativity.
