Oxygen almost always keeps an oxidation number of -2.
Since the overall ion has a charge of -1 you just have to balance the ion.
2*-2 for the oxygen = - 4
In order for the overall charge to be -1, the chlorine must have a +3 oxidation numbers.
The oxidation number of Cl in ClO2 is +3. This is because oxygen typically has an oxidation number of -2, and there are two oxygen atoms in ClO2, giving a total of -4. To balance the charge, Cl must have an oxidation number of +3.
The oxidation state of Cl in ClO2 is +3. This is determined by assigning oxygen an oxidation state of -2 and knowing that the overall charge of the compound is 0. Since there are two oxygen atoms with an oxidation state of -2 each, the oxidation state of Cl must be +3 to balance it out.
The oxidation number of chlorite (ClO2-) is +3. In this ion, the oxygen has an oxidation number of -2 and since there are two oxygen atoms, that gives a total of -4. To balance the charge of -1 for the chlorite ion, the chlorine atom must have an oxidation number of +3.
The oxidation number of Cl in potassium chlorate (KClO3) is +5. This is because the oxidation number of K is +1 and the oxidation number of O is -2. By using the sum of the oxidation numbers in the compound, the oxidation number of Cl can be calculated to be +5.
The oxidation number for Cl in Cl4 is -1. Since Cl is a halogen, it typically has an oxidation number of -1 when it forms compounds.
The oxidation number of Cl in ClO2 is +3. This is because oxygen typically has an oxidation number of -2, and there are two oxygen atoms in ClO2, giving a total of -4. To balance the charge, Cl must have an oxidation number of +3.
The oxidation state of Cl in ClO2 is +3. This is determined by assigning oxygen an oxidation state of -2 and knowing that the overall charge of the compound is 0. Since there are two oxygen atoms with an oxidation state of -2 each, the oxidation state of Cl must be +3 to balance it out.
In barium chlorite, Ba(ClO2)2, the oxidation state of barium (Ba) is +2. Each chlorite ion (ClO2-) has a charge of -1. Within the chlorite ion, the oxidation state of oxygen is -2, so for two oxygen atoms, that totals -4. To balance this, the oxidation state of chlorine must be +3. Therefore, the oxidation state of Cl in Ba(ClO2)2 is +3.
ClO2 → Cl + O2
Chlorite ( ClO2- ) is the base anion of chlorous acid: HClO2, the Oxidation number (or state) of Cl in this compoud is +3 according to this:oxidation state−1+1+3+5+7anion namedchloridehypochloritechloritechlorateperchlorateformulaCl-ClO−ClO2−ClO3−ClO4−
The oxidation number of Cl in potassium chlorate (KClO3) is +5. This is because the oxidation number of K is +1 and the oxidation number of O is -2. By using the sum of the oxidation numbers in the compound, the oxidation number of Cl can be calculated to be +5.
The oxidation number of chlorite (ClO2-) is +3. In this ion, the oxygen has an oxidation number of -2 and since there are two oxygen atoms, that gives a total of -4. To balance the charge of -1 for the chlorite ion, the chlorine atom must have an oxidation number of +3.
The oxidation number for Cl in Cl4 is -1. Since Cl is a halogen, it typically has an oxidation number of -1 when it forms compounds.
The oxidation number for Cl in ClO3 is +5. This is because oxygen has an oxidation number of -2 and there are 3 oxygen atoms in ClO3, resulting in a total oxidation number of -6. The overall charge of the ion is -1, so the oxidation number of Cl must be +5 to balance the charges.
The oxidation number of N in NCl3 is +3. This is because the oxidation number of Cl is -1, and there are three Cl atoms in NCl3, so the overall charge must be balanced by N having an oxidation number of +3.
-1 is most common, but Cl can exhibit oxidation numbers from -1 to +7 in its compounds.
In OCl (hypochlorite), the oxidation number of Cl is -1. This is because oxygen has an oxidation number of -2 and the overall charge of the OCl ion is -1, meaning that Cl must have an oxidation number of -1 to balance the charge.
