Arrange the following oxoacids of chlorine in increasing order of their acidic strength: , , , . — p Block Elements Chemistry Question

💡 Solution & Explanation

The acidic strength of oxoacids of the same halogen increases with an increase in the oxidation number of the halogen. The oxidation states of Cl are +1, +3, +5, and +7 respectively. Thus, acidic strength order is $HClO < HClO_2 < HClO_3 < HClO_4$.
