The chromyl chloride test is used to detect chloride ions. Which of the following chlorides will NOT — Qualitative and Quantitative Analysis Chemistry Question

💡 Solution & Explanation

Covalent or partially covalent heavy metal chlorides like $HgCl_2, AgCl, PbCl_2$, and $SnCl_2$ do not ionize sufficiently in concentrated $H_2SO_4$ to yield the $Cl^-$ ions necessary for the formation of chromyl chloride ($CrO_2Cl_2$).
