HClO2 is a stronger acid than HClO.Click to see full answer. In this manner, why is HClO2 stronger than HClO?The general rule is that the acid is stronger if it has more O atoms in a series such as this. HClO4, perchloric acid, is a very strong acid as is HClO3. HClO2 is a weak acid and HClO is even weaker. Thus we see more oxygen atoms means more possible strutures & which means stronger the acid.Furthermore, is HClO a strong acid? Strong Acid: dissolves and dissociates 100% to produce protons (H+) 1. seven strong acids: HCl, HBr, HI, HNO3, H2SO4, HClO4, & HClO3 2. any acid that is not one of the seven strong is a weak acid (e.g. H3PO4, HNO2, H2SO3, HClO, HClO2, HF, H2S, HC2H3O2 etc.) Correspondingly, is HClO or HBrO a stronger acid? HBrO is a little stronger than HIO because Br is stronger in electronegativity than I. HClO is a little stronger than HBrO because Cl is stronger in electronegativity than Br. HClO 2 is a little stronger than HClO because it contains two electronegative oxygens.Which is stronger oxidising agent HOCl or HClO4?Explanation: hocl is stronger oxidizing agent than hclo4 because it has the lowest oxidation state and hence it is a stronger oxidizing agent.
