Question

Which of the following is used to damask zinc from the zinc-cyanide complex?

• A. Tiron
• B. Potassium iodide
• C. Chloral hydrate
• D. Triethanolamine

Hint:

Tiron is commonly used in chemical processes to release zinc from its complexes, making it an essential reagent in damasking procedures.

Answer 1

The Correct Option is A

Step 1: Understanding damasking in zinc cyanide complex.
Damasking is a process used to remove or release zinc from a zinc-cyanide complex. This process typically involves a chemical reagent that can break the bond between zinc and cyanide.
Step 2: Analyzing the options.

• (A) Tiron: Correct. Tiron is an effective reagent that can remove zinc from its complex with cyanide, making it the correct choice for this process.
• (B) Potassium iodide: Incorrect. Potassium iodide is not used for damasking zinc from the zinc-cyanide complex.
• (C) Chloral hydrate: Incorrect. Chloral hydrate is not typically involved in the process of damasking zinc.
• (D) Triethanolamine: Incorrect. Triethanolamine is not a reagent used for damasking zinc from the zinc-cyanide complex.

Step 3: Conclusion.
Tiron is the most effective reagent for damasking zinc from the zinc-cyanide complex. Final Answer:} Tiron.
