Question

Which among the following is NOT a mineral of chlorine?

• A. Horn silver
• B. Cryolite
• C. Carnalite
• D. Sylvine

Hint:

To identify minerals of chlorine, look for halides that contain chloride ions, such as sylvine and cryolite.

Answer 1

The Correct Option is A

Step 1: Understanding minerals of chlorine.
Chlorine is a halogen, and minerals containing chlorine are typically halide minerals. Some common minerals of chlorine include sylvine, cryolite, and carnallite.
Step 2: Analyzing the options.
(A) Horn silver: Correct — Horn silver is primarily composed of silver chloride (AgCl), which is a mineral of chlorine. However, this is not typically considered a mineral of chlorine itself.
(B) Cryolite: This is a mineral of chlorine, as it contains sodium fluoride and sodium chloride.
(C) Carnalite: This mineral contains potassium chloride and magnesium chloride, making it a mineral of chlorine.
(D) Sylvine: This is a mineral of chlorine, primarily consisting of potassium chloride.
Step 3: Conclusion.
The correct answer is (A) Horn silver.
