The oxidation state of chlorine in potassium chlorate (KClO3) is +5.
The oxidation state of phosphorus in PCl5 is +5. Each chlorine atom contributes an oxidation state of -1, so the sum of the oxidation states in PCl5 equals the overall charge of the molecule, which is 0.
The oxidation state of ICl is +1 for iodine and -1 for chlorine. This is because iodine is more electronegative than chlorine, resulting in a net oxidation state of +1 for the molecule.
Go to the periodic table and look at the oxidation states for lithium and for chlorine. You will notice that there is only one value for lithium, and several values for chlorine. Therefore, the oxidation state for lithium is going to determine the answer for "how many chlorines." Now look at chlorine. Since the oxidation state for lithium is a positive value, which of the oxidation states for the chlorine would be applicable (remember lithium chloride is an ionic bond)? Identify the appropriate oxidation state for chlorine, and adjust accordingly.
In ammonium chloride (NH4Cl), the oxidation state of nitrogen is -3, hydrogen is +1, and chlorine is -1.
To find the oxidation number of chlorine, consider that chlorine typically has an oxidation number of -1 in its compounds. However, in certain situations, such as when bonded with oxygen or other halogens, chlorine can have different oxidation states. It's important to follow the usual oxidation number rules and balance the charges in the compound to determine the oxidation number of chlorine.
The oxidation number of chlorine in the compound PbCl is -1. Each chlorine atom in PbCl has an oxidation number of -1, as lead has a fixed oxidation number of +2.
Chlorine has its highest oxidation number of +7 in perchloric acid (HClO4).
Chlorine has an oxidation number of +5 in compounds such as perchlorate (ClO4-). This is due to the electronegativity of oxygen, which causes chlorine to have a higher oxidation state in the compound.
The oxidation state of chlorine in HCl is -1. In HCl, hydrogen is assigned an oxidation state of +1 because it usually has a +1 charge when bonded to nonmetals. Since the overall charge of HCl is 0, the chlorine must have an oxidation state of -1 to balance the charge.
The oxidation number of chlorine in PbCl2 is -1. This is because the overall charge of PbCl2 is 0, and since there are two chlorine atoms in the compound, each chlorine atom must have an oxidation number of -1 to balance with the +2 oxidation number of lead (Pb).
The oxidation state of chlorine in potassium chlorate (KClO3) is +5.
The most common oxidation number of chlorine is -1.
The oxidation state of chlorine in bleaching powder (CaOCl2) is +1. This is because calcium has an oxidation state of +2 and oxygen has an oxidation state of -2, so the total charge must be balanced by the chlorine with an oxidation state of +1.
The oxidation number of chlorine in AlCl4 is -1. Since aluminum has an oxidation number of +3, the overall charge of the AlCl4 ion is -1, meaning each chlorine atom has an oxidation number of -1 to balance the charge.
-1 is found in chlorides. But chlorine can have other oxidation numbers up to +7 in its compounds.
The oxidation number of chlorine in MgCl2 is -1. Magnesium is a group 2 element with an oxidation number of +2, and since the compound is neutral, the total oxidation number of the two chlorine atoms must equal -2, making the oxidation number of each chlorine atom -1.
