The chlorate ion is ClO3-. Some text books say that the oxidation number of the whole ion is equal to the charge, so in this cas it would be -1. However most teachers would sya that oxidation numbers only refer to atoms. So working out the oxidation numbers:-
oxygen is -2, (using the rule, or if you use the he electronegativity method- gives the same answer as O is more electronegatoive than Cl)
the sum of oxidation numbers of Cl and O are -1 (the charge on the ion) - I'll call the oxidation number of Cl OxCl
-1 =OxCl + (3* -2)= OxCl -6
therefore OxCl = +5

What are the uses of the chlorate ion?
It is generally used as an oxidizer because it contains chlorine in +5 oxidation state.
What is the oxidation number of S in S2O8?
This is the thiosulfate ion. Sulfur shows +6 oxidation number.
What is oxidation number of carbon in Hydronium?
In the hydronium ion (H3O+), the oxidation number of carbon is +3.
What is the oxidation number of the molecular ion ammonium NH4 in ammonium chloride NH4Cl?
The oxidation number of the ammonium ion is +I.
What is the oxidation number of an ion?
Whatever the charge on that ion is.
What are the uses of the chlorate ion?
It is generally used as an oxidizer because it contains chlorine in +5 oxidation state.
What is the oxidation state of chlorine in the chlorate ion ClO3?
Oxygen in compounds is almost always in the -2 formal charge, and the charges of all atoms must add to the overall charge. 3 x -2 + (Cl) = -1, thus (Cl) = +5.
What is chemical formula for the chlorite ion?
The chemical formula for chlorite ion is ClO2- and the other oxy-anions of chlorine are (IUPAC names in parentheses); ClO- : Hypochlorite ion [ Chlorate(I) ion ] ClO3- : Chlorate ion [ Chlorate(V) ion ] ClO4- : Perchlorate ion [ Chlorate(VII) ion ]
What is the oxidation number of S in S2O8?
This is the thiosulfate ion. Sulfur shows +6 oxidation number.
What is oxidation number of carbon in Hydronium?
In the hydronium ion (H3O+), the oxidation number of carbon is +3.
What is the oxidation number of the molecular ion ammonium NH4 in ammonium chloride NH4Cl?
The oxidation number of the ammonium ion is +I.
What is the oxidation number of an ion?
Whatever the charge on that ion is.
How do you get sodium chlorate from formula NaClO3?
It contains the sodium ion Na+ and the chlorate ion ClO3- Since sodium is the positive ion (cation) you name it first, then you name the chlorate ion second because it is the anion (negative ion). so the name of the compound is sodium chlorate.
What is the chemical formula for a chlorite ion a chloride ion and a chlorate ion?
Chloride: Cl- Chlorite: ClO2- Chlorate: ClO3-
How is charge related to oxidation number?
the charge on a mono-atomic ion is the same as the oxidation number, for a polyatomic ion the charge is the sum of the oxidation numbers of its constituent elements.
What is the oxidation number of mercury in the mercurous ion?
thr oxidation number of mercury is + 2
With monatomic species what does the oxidation number indicate?
The charge. Cations and anions have an oxidation number equal to their charge, for example in Fe2+, Fe hasan oxidation number of +2 and in S2- S has an oxidation number of -2. Uncharged atoms have zero oxidation number.
