7.29 Give the reason for bleaching action of Cl₂.

<p><strong>7.29</strong></p><p>Moist chlorine is a good reducing agent because it can accept electrons from other species as it is very electronegative.</p><p> (iii) The bleaching action of chlorine is due to oxidation by nascent oxygen produced. This nascent oxygen can be produced by</p><p>Chlorine dissolves in water in absence of sunlight and forms hydrochloric acid and hypochlorous acid (HOCl)</p><p>Since hypochlorous acid is not much stable it decomposes giving nascent oxygen. Cl₂ + H₂O&nbsp; HCl + HOCl</p><p>HOCl HCl + [O]</p><p>This [O] is called as nascent oxygen. This nascent oxygen is responsible for bleaching action.</p><p>NOTE: Since chlorine has the ability to kill harmful micro-organism it also acts as a good disinfecting agent.</p>
