And "sodium chlorate(V)" is the old sodium chlorate, NaClO_3.
ClO_4^-; i.e. Cl(+VII), "perchlorate."
ClO_3^-; i.e. Cl(+V), "chlorate."
ClO_2^-; i.e. Cl(+III), "chlorite."
ClO^-; i.e. Cl(+I), "hypochlorite."
Cl^-; i.e. Cl(-I), "chloride."
And these are the salts of the chlorine oxyacids......."perchloric acid", HClO_4, ......."chloric acid", HClO_3, HO_2Cl, "chlorous acid", HOCl, "hypochlorous acid". Confused yet? You do not have to know these names at A level, or even as a first year undergrad. You should know how the oxidation noombers are assigned. Do you?
