The Chromyl Chloride test is a definitive, classical qualitative laboratory test. What are the stric — d and f Block Elements Chemistry Question

💡 Solution & Explanation

The test strictly requires concentrated $H_2SO_4$ to dehydrate the mixture and vaporize the product. The reaction generates deep orange-red fumes of Chromyl Chloride ($CrO_2Cl_2$). Note: Covalent chlorides (like $HgCl_2$, $AgCl$) fail this test.
