Chlorate ion
The oxyanion of phosphoric acid is called phosphate.
Chlorite Ion
No, the name of an oxyanion is not based on the amount of a metal in the ion. The name of an oxyanion is determined by the oxidation state of the element and the number of oxygen atoms in the ion. The metal in the ion may play a role in determining the charge or oxidation state of the element, but it does not directly determine the name of the oxyanion.
The oxyanion of the acid HC2H3O2(aq) is acetate ion (C2H3O2^-).
An oxyanion is in the form of AxOy, where A is a chemical or polyatomic ion, and O is an oxygen.
ClO2^- is chlorite anion Do not confuse with ClO3^- is chlorate anion Cl^- is chloride anion.
Formula: ClO-
The symbol for the oxyanion perchlorate ion is ClO4-.
The oxyanion of chlorine that contains the most oxygen atoms is perchlorate (ClO4-).
This anion is called metavanadate.
Formula: ClO-
chlorateClO3- is the chlorate polyatomic ion. It has a -1 charge, so it bonds easily with group 1 metals. Potassium chlorate (KClO3) is a common example compound that you may encounter in chemistry.
