Aqueous solution of which of the following cation gives precipitate with potash alum? — Redox Reactions and Volumetric Analysis Chemistry Question

💡 Solution & Explanation

Step 1: Peroxynitric acid (HNO4) contains nitrogen in the +5 oxidation state. Hydrolysis of HNO4 yields nitric acid (HNO3) and hydrogen peroxide (H2O2). Step 2: The nitrogen-containing product is nitric acid, which has the "-ic" suffix. Step 3: Therefore, the nitrogen-containing product is an oxyacid with an "-ic" suffix, matching option (a).
