In the disproportionation reaction CI2 + H2Omc021-1.jpgHCIO + HCI, what describes the oxidation states of the substance Cl?
Cl has an oxidation number of 2 in Cl2. It is then reduced to Cl with an oxidation number of 1 in both HCl and HClO.
Cl has an oxidation number of \u20131 in Cl2. It is then oxidized to Cl with an oxidation number of 1 in both HCl and HClO.
Cl has an oxidation number of 0 in Cl2. It is then reduced to CI- with an oxidation number of \u20131 in both HCl and HClO.
Cl has an oxidation number of 0 in Cl2. It is then reduced to CI- with an oxidation number of \u20131 in HCl and is oxidized to Cl+ with an oxidation number +1 in HClO.<\/p>\n\n\n\n
The Correct Answer and Explanation is :<\/strong><\/mark><\/p>\n\n\n\n The correct answer is:<\/p>\n\n\n\n Cl has an oxidation number of 0 in Cl2. It is then reduced to Cl\u2013 with an oxidation number of \u20131 in HCl and is oxidized to Cl+ with an oxidation number of +1 in HClO.<\/strong><\/p>\n\n\n\n In the disproportionation reaction:<\/p>\n\n\n\n [ \\text{Cl}_2 + \\text{H}_2\\text{O} \\rightarrow \\text{HCl} + \\text{HClO} ]<\/p>\n\n\n\n The chlorine (Cl) undergoes both oxidation and reduction, which is why it’s called a disproportionation reaction. Let’s break down the oxidation states of chlorine in the reaction:<\/p>\n\n\n\n Thus, chlorine undergoes disproportionation, where one atom is reduced and the other is oxidized. This reaction demonstrates a classic case of disproportionation where a single substance (Cl2) reacts to form products with two different oxidation states of the same element.<\/p>\n","protected":false},"excerpt":{"rendered":" In the disproportionation reaction CI2 + H2Omc021-1.jpgHCIO + HCI, what describes the oxidation states of the substance Cl?Cl has an oxidation number of 2 in Cl2.

\n
Chlorine (Cl2) is a molecule of two chlorine atoms. In elemental chlorine, the oxidation state of each chlorine atom is 0<\/strong>. This is because Cl2 is in its most basic, unoxidized state.<\/li>\n\n\n\n
In hydrochloric acid (HCl), chlorine forms an ionic bond with hydrogen. The oxidation state of chlorine in HCl is -1<\/strong> because the hydrogen atom has an oxidation state of +1, and chlorine must balance it to achieve a neutral molecule.<\/li>\n\n\n\n
In hypochlorous acid (HClO), chlorine is bonded to hydrogen and oxygen. The oxidation state of chlorine here is +1<\/strong>. Oxygen typically has an oxidation state of -2, and hydrogen is +1. For the molecule to be neutral, chlorine must have an oxidation state of +1 to balance the -2 from oxygen and +1 from hydrogen.<\/li>\n<\/ol>\n\n\n\nRedox Process (Oxidation and Reduction):<\/h3>\n\n\n\n
