Which of the following radical does not liberate gas with (Zn + dil. HCl) on warming? — Redox Reactions and Volumetric Analysis Chemistry Question

💡 Solution & Explanation

Step 1: Sulfur trioxide (SO3) has sulfur in the +6 oxidation state. Hydrolysis of SO3 at room temperature is a non-redox reaction that produces sulfuric acid (H2SO4). Step 2: In H2SO4, the suffix of the oxyacid name is "-ic" (sulfuric acid). Step 3: Therefore, the product of complete hydrolysis of the sulfur atom is an oxyacid with an "-ic" suffix, matching option (a).
