If the name of the acid ends in the letters "ic" and the acid contains oxygen, the name of the anion formed from it replaces the "ic" with "ate". If the name of the acid ends in the letters "ous" and the acid contains oxygen, the name of the anion formed from it replaces the "ous" with "ite." If the name of acid ends in the letters "ic" and the acid does not contain oxygen, the name of the anion formed by the acid changes "ic" to "ide", and if the name of the acid begin with "hydro", these letters are deleted from the name of the anion.
