Chromyl Test is performed to confirm:
Correct answer: A. Cl− ions
- A. Cl− ions
- B. SO4−2 ions
- C. PO4−3 ions
- D. Cr+3 ions
Explanation
Explanation:The chromyl chloride test is performed to detect chloride ions in the qualitative analysis. When any chloride salt for example sodium chloride (NaCl) is heated with acidified potassium dichromate, it gives fumes of chromyl chloride which is used to be in orange-red color. This confirms the presence of chloride ions in the salt.The chromyl test is not used to confirm the presence of sulfate ions (SO4-2). The chromyl test is not used to confirm the presence of phosphate ions (PO4-3). The chromyl test is also not used to confirm the presence of chromium ions (Cr+3).

About Spectroscopy and Analysis
Spectroscopy studies how substances absorb, emit or interact with electromagnetic radiation. Coverage includes ultraviolet-visible absorption, infrared identification of functional groups, Beer-Lambert law, spectral interpretation and the use of spectroscopic data to identify or determine the concentration of chemical substances.
