The correct answer to this question is "5." the oxidation number of cl in ClO3 will be a positive 5 because oxygen is naturally a -2 charge. times that by three and then account for the negative charge of the CLO3- ion.
Answer is: the oxidation number of Cl (chlorine) in chlorate ion is +5.
Chlorate ion (ClO₃⁻) has negative charge.
One oxygen atom in this anion (negatively charged ion) has the oxidation number -2. There are three oxygen atoms in chlorate anion.
x + 3 · (-2) = -1.
x = -1 + 6.
x = +5; the oxidation number of chlorine.
